Parameter Tuning and Simulation of PID Controller for Reactor Power Control System

基于MATLAB计算仿真工具,对反应堆功率控制系统进行了PID参数整定。利用频率法和临界比例度法来整定PID控制器参数,并且用MATLAB来实现仿真。分析结果表明:经过PID控制器调节后,功率控制系统各性能指标明显得到了改善,系统响应更快,调节时间更短,超调量更低,系统能够更快稳定。PID控制器提高了控制系统的适应能力和鲁棒性能,改善了系统品质。

Based on the MATLAB tool, parameter of the PID controller is tuned for reactor power control system. Frequency method and critical proportional is used to tuning PID eontroller parameters, and simulation uses MATLAB. The analysis results show that： after the adjustment of the PID controller, power control system performanee is signifieantly improved. System responses faster, the adjustment time is shorter, overshoot is lower, the system is capable of faster stabilization. PID controller has improved the adaptability and robust performante of the control system, and ameliorate the system quality.
