Taiwanese economy is extremely export-oriented. However, Taiwan also starts to actively look for opportunities for participation, because of the slowdown of multinational liberalizations, and as a result of the advance of the regional economic integration trend. As an example, Taiwan vigorously participates in FTAs with countries in Asia and Central America. International economic conditions are significantly...
Usually the missile attitude control process in a large flight envelope has strong time-varying and nonlinear characteristics, so the controller parameter is difficultly scheduled with conventional PID control approach. In this study a linear active disturbance rejection control approach based on reduced-order linear extended state observer is proposed. The approach is employed to the attitude controller...
In this paper, we discuss how to synthesize a stabilizably robust controller for a ball and plate system (BPS). In order to reduce the fragility in its robust controller synthesis, a loop-shaping method in terms of a normalized right coprime factor (NRCF) uncertainty description for the BPS is thus employed. In effect, the design of weighting functions for the BPS loop-shaping is a decisive factor...
How to improve the energy utilization efficiency and prolong survival time of network has been an important issue in the field of wireless sensor network. In view of the energy-constrained situation in wireless sensor networks, we introduce game theory with non-cooperative game mode to optimize the network energy distribution. Regard the sensor nodes as rational participants in the decision-making...
The outbreak of the global financial crisis in 2008 and China's more strict foreign capital policy have led to the hither to unknown dilemma for foreign capitals. More and more foreign disinvestment occurred and it has brought a great risk to the development of China's economy. This essay establishes a cross market disinvest risk conduction model, analyses the conduction mechanism of the risk of foreign...
Fuzzy measure is a kind of set function which can represent the interaction of IF-THEN rules in reasoning, and fuzzy integral is decision tool in information fusion and process control problem. Although the fuzzy cognitive map model is an effective approach in reason process and the intuitionistic fuzzy cognitive map model introduces intuitionistic fuzzy set which uses the hesitancy as the indeterminacy...
The principle and characteristics of Initiation System was introduced in this paper. The numerical simulation of the system was studied. Three mathematical models were analysed and discussed. Theoretical bases are provided for optimization design of the system.
Thermocouple sensor for temperature measurement has been widely used, however, the increase of precision is constrained due to the shortcoming of hardware based or table look up method, especially with nonlinear adjustment and cold end compensation. A new method was presented to compensate nonlinearity and cold-side-offset for signal processing of thermocouple with RBF neural networks. The structure...
The energy-saving gap of building is serious. In practical matters of building engineering, the input process of time-varying system can be divided into several stages. In every stage, the system has its own rules and features. At present, various evaluation methods are slow in solving this matter. Cascade neural network can properly describe the growth continuity of each part of building energy-saving...
There are at least three paths to solve the value innovation and value-added conditions for China construction industry. This paper synthesizes three perspectives to construct a frame and strives to rethinks the delimma for the development of China construction industry. From the institutional transition economics view, it finds that The reform of industry and the breakthrough of operational mechanism...
Starting from innovative management prospective, in connection to construction energy-saving gap, and with construction energy-saving chain management as theme, this paper studies the characteristic of innovative management of construction energy-saving and how to organize and operate in Chinese architecture industry. Basic on system control theory, author introduced status parameters (variables)...
If second order non-autonomous circuit with damping satisfies certain conditions, the oscillations should contain two components, the self-excited and forced oscillations. This paper, on the theoretical basis of power balance, finds the critical value of this condition. With regard to non-autonomous circuits with no damping, active power can keep balance under any situations. The two oscillation components...
This paper deals with the regulation of water flow in an open channel with arbitrary cross sections modeled by the nonlinear Saint-Venant equations. The characteristic form of the Saint-Venant initial-boundary value problem is established in terms of Riemann invariants. In order to develop the boundary control laws for a canal with arbitrary cross sections, a general boundary control design approach...
Based on the input-output model and Research & Development (R&D) and other spillover effects theories the author analyses empirically R&D spillover effect among 42 industries of Hebei Province. The author want to identify the industries of larger and smaller spillover effect with the potential spillover effects, analyze the causes and present conclusions and recommendations...
Dynamic thermal comfort control can effectively improve the levels of comfortable feeling, energy-saving, and human health. Traditional control theories and methods based on accurate physical model can not solve the control problems met during analyzing and controlling thermal comfort because of difficulties in obtaining the accurate model of a thermal environment. This paper presented a novel control...
In order to most effectively utilize the wind energy and improve the efficiency of wind generation system, an optimum control strategy of doublyfed induction generators (DFIG) was proposed, which made the system operation for both the maximum wind enemy captured below the rated wind speed. Based on the wind turbine characteristics and basic electromagnetic relationship of DFIG the mathematical models...
Danjiangkou city is the main part of Danjiangkou reservoir area which is the catchments area for the South-to-North Water Transfer (middle line) project in China. Soil erosion and the subsequent pollutants loss are important influencing factors on its water quality. In this paper, soil erosion rate were analyzed based on 137Cs tracer technique, and the mathematic models were simulated among 137Cs...
Based on building energy-saving current situation and the uncertainty analysis in energy-saving chain management, this paper describes the Leak and Spread Mechanism of Building energy-saving in the process of construction to energy-saving Building, constructs the dynamic expansion model to show the growth and expansion trend of construction energy-saving inappropriate information, presents the information...
Under a regulation imposed by a regulatory authority, a general risk model is studied with stationary independent increments. The regulatory authority's problem is to exercise a regulation barrier and penalties to protect the insured with minimum cost. For an insurance firm with the given regulation, it has to maximize its long run average profit per unit time by seeking an investment-dividend policy...
Aiming at the phenomenon of premature convergence and later period oscillatory occurrences, an adaptive particle swarm optimization algorithm with the changes of the population diversity was proposed. In the algorithm, the adaptive exponent decreasing inertia weight and a dynamic adaptive changing threshold were proposed, the satisfied particle of threshold will be mutation by the average distance...
