为改善静止无功补偿器传统PID电压调节器的动态调节效果,增强其自适应能力,提出了一种基于神经元控制双层结构生物智能控制器的设计方法,其一级控制单元采用神经元控制,二级控制单元采用传统PID控制,神经元控制器根据实时误差动态调节PID控制器输入的给定值以提高控制效果.采用MATLAB中S-function模块并结合S-函数编程方法建立了控制器的仿真模型,然后用其替代静止无功补偿器控制系统中的PID电压调节器.仿真结果表明:基于神经元的生物智能控制电压调节器能快速、灵活地调节电压,维持系统电压稳定.

In order to improve dynamic regulation effect of traditional PID voltage regulator for SVC and enhance its adaptive capacity, a design method of two-level biological intelligence controller based on neuron adaptive control was proposed. The master control unit and the secondary control unit of the biological intelligent controller were designed using neuron adaptive control and conventional PID control. The neuron adaptive controller can adjust dynamically the set-point of PID controller according to the real-time control error to improve control effect. The simulation model of biological intelligence controller was built by using S-function module and programming method based on S-function in MATLAB, then the conventional PID voltage regulator of SVC control system was replaced by it. The simulation results show that the voltage regulator based on biological Intelligence controller can adjust quickly and flexibly the voltage to maintain stabilization of system voltage.
