The problems of the discrete fuzzy controller design for the ship motion system and the stability analysis for the closed-loop discrete fuzzy system are studied. Firstly, a discrete T-S fuzzy model of the ship motion system is established; then, by using the method of parallel distributed compensation, a new sufficient condition to check the stability of the closed-loop discrete T-S fuzzy system is...
In this paper, periodic learning control is presented for deterministic periodic auto-regressive exogenous systems. The control problem is approached in a certainty equivalence framework, of which a periodic learning identification algorithm is formed to estimate the periodic time-varying parameters, and the only prior knowledge is the periodicity. The learning algorithm updates the estimates periodically,...
An adaptive IMC-PID control method based on neural network (NN) is proposed for the typical industrial process in this paper. The conventional IMC-PID provides a convenient method of tuning parameter according to the requirement of the control performance for closed-loop system because it has only one regulable parameter. But when the parameters variation and uncertainty factors are included in the...
To the best of our knowledge, this is the first paper focus on the adaptive impedance control of robot manipulators with consideration of joint flexibility and actuator dynamics. Controller design for this problem is difficult, because each joint of the robot have to be described by a 5th-order cascade differential equation. In this paper, a backstepping-like procedure incorporating the model reference...
This research aims to construct sliding mode control (SMC) system that decreases chattering in controlled object of discrete time system. In conventional SMC, chattering has been generated by turbulence's influencing the state, and repeating operation that jumps over switching hyperplane. Then, we thought about switching hyperplane that always moved according to the change in the state. The feature...
In this paper, a new control approach is proposed for the transient stabilization of a single-machine infinite-bus power system. The proposed method is based on an LPV (linear parameter varying) modelling of the nonlinear power system and gain-scheduled output feedback control. It is well-known that when large disturbances or a fault occurs, the nonlinearity inherent in power systems can no longer...
This paper proposes an improved Linear Matrix Inequality (LMI) approach for the synthesis of Static Output Feedback (SOF) Fault-Tolerant Control (FTC). A novel slack variable is introduced into the matrix inequalities, which provides an additional degree of freedom to compute the numerical solution. Subsequently, an improved iterative algorithm is developed to obtain an optimal SOF gain with less...
The disturbance observers have been used to estimate the disturbance in the plant. Several papers on design methods of disturbance observers have been published. The parametrization of all disturbance observers for plants with any output disturbance was clarified. However, no paper examines the parametrization of all disturbance observers for plants with any input disturbance. In this paper, we clarify...
Repetitive processes are a distinct class of two-dimensional (2D) systems (i.e. information propagation in two independent directions occurs) of both systems theoretic and applications interest. They cannot be controlled by direct extension of existing techniques from either standard (termed 1D here) or (often) 2D systems theory. In this paper we begin the development a systems theory for a model...
This paper proposes an optimal control approach for the robust control design problem of the linear time-delay systems, which takes parameter uncertainties and state delay into account. It is shown that the robust control problem can be equivalently transformed into an optimal control problem with the amount of plant uncertainties indirectly reflected in the performance index. By introducing algebraic...
Urban terrain is complex and they present a very challenging and difficult environment for simulating virtual forces as well as for rendering. The objective of this work is to research on binary space partition technique (BSP) for modeling urban terrain environments. BSP is a method for recursively subdividing a space into convex sets by hyper-planes. This subdivision gives rise to a representation...
Based on the analysis of the complexity of a kind of huge complicated building the architecture of the intelligent management system for these buildings were provided and then studied using the tools such as large system theory, artificial intelligence and computer control theory. The intelligent system has the hierarchical, multi-level and multi-section structure. The subjects including the system...
This paper presents the design of an IPT security camera system with the integration of a secure wireless communication scheme. Two innovative circuits known as an LCL tuning circuit and a multi-phase interleaving system have been applied to the design of the IPT pick-up circuit. A wireless local area network (WLAN) using 802.11 g protocol has been chosen to realise the high bandwidth communication...
This thesis proposed a novel embedded system framework (ESF) for data collection of semiconductor and optoelectronic manufacturing equipment. Most present equipment engineering data collection systems acquire engineering data from equipment to remote data collection and analysis servers. In this work, devices implemented ESFs are embedded in the equipment for data collection and some data analysis...
The paper presents a formal design methodology for reconfigurable, modular digital controller logic synthesis. The project of embedded controller starts from behavioral, graphical hierarchical and concurrent state machine description in Unified Modeling Language (UML). After the hierarchical encoding of nested and concurrent superstates, the UML state machine diagram can be directly and automatically...
