Based on existing power line structures of multi-path transmission channel model and taking the measured data of practical low voltage power-line communication channel magnitude of the frequency response within the range form 0.5MHz to 20MHz as samples, The particle swarm optimization algorithm of self-adaptive parameter based on ant colony algorithm (AS-PSO) is applied to the multi-parameter identification...
A suitable controller needs to be designed in order to acquire the highest performance of the electro-hydraulic system. A classical PID controller for the models attained has been introduced. The expert system is applied in the PID tunning. In contrast, the traditional tunning method is used. Both methods, simulation and experiment results are given.
According to phenomenon of suspension temperature rising lead to vehicle state change,a research method of gas chamber length of hydro-pneumatic spring is presented. The diagram of single barrel hydro-pneumatic spring is given. With regard to the structural feature of single barrel hydro-pneumatic spring, the system elastic force is deduce respectively according to two situations that known and unknown...
In order to improve the intellectual property services to the contribution of economic development, taking Intellectual Property services as research object, the approach to control of large scale system for coordinated development between Intellectual Property services and economic development is presented. Its corresponding mathematical model is established by applying theory and method of large...
A unified power quality conditioner (UPQC) using model predictive control (MPC) is proposed for improving power quality in a power distribution system. MPC is applied into UPQC to regulate the supply current and the load voltage to the desired reference signals in spite of the existence of harmonic distortions in the supply voltage and the load current, possible sags or swells in the supply voltage,...
In this work, an optimization algorithm is presented for nonlinear analysis of space bar structures. The major character of the optimization algorithm is that the equilibrium state with elastic-plastic large deformation is chosen as the study object. Constitutive law adopts linearly elastic and power hardening model. The objective function is defined. The optimization problem is established for nonlinear...
Through analyzing the principle of spindle drive of high speed winding machine for synthetic filament, on the basis of actual apparent density, a kind of control model, control algorithm and its implementation scheme to realize spindle drive for uniform velocity winding is researched and established. The computer control technique of spindle drive realized by using Programmable Computer Controller...
In view of existing situation of Green Supply Chain (GSC) and the control issues of coordinate management with large scale systems for GSC, the control channels of large scale systems for coordinate development of GSC are discussed by applying the theory and method of large scale systems based on large system cybernetics. The theoretical basis and available means for the scientific design and effective...
