用于TCSC阻抗控制的CMAC和PID复合策略

CMAC AND PID COMPOSITE CONTROL STRATEGY FOR TCSC IMPEDANCE CONTROL

TCSC的阻抗控制是实现TCSC其他控制功能的基础。为更好地实现TCSC对命令阻抗的响应,采用了一种新型阻抗控制策略——小脑模型神经网络(Cerebella Model Articulation Controller,CMAC)与PID复合控制策略。该控制策略能够实现被控对象的逆动态模型,同时保证系统能有效地抑制扰动,具有足够的稳定性。在Matlab/Simulink仿真环境下搭建两区域四机系统进行仿真,结果证实了该控制策略的有效性。

TCSC impedance control is the foundation of the realization of the other control functions for the TCSC. To obtain the better response of the TCSC impedance control, a novel control strategy-the composite control strategy with CMAC and PID, was applied in the paper. The control strategy can realize the inverse dynamic model, mitigates the disturbance, and ensures the system stability. The Madab/Simulink software is used to build the two-area four-machine system and the simulation results indicate the feasibility of the control strategy.
