摘要：研究水轮发电机组优化控制问题,电能的电压和频率应保持稳定值,保证安全供电。由于水轮发电机组是一个非线性、时变的复杂系统,传统PID控制算法难以对其做出精确控制,导致系统稳定过程时间长,超调量大。为解决上述问题,提出一种CMAC与PID复合控制的水轮发电机组控制系统。复合控制方法利用CMAC进行前馈控制,加快系统控制响应速度,减小超调量,从而提高控制精度;利用PID实现反馈控制,用来保证系统稳定并减少系统扰动。仿真结果表明,CMAC-PID控制方法提高了系统的控制精度,系统超调量更小,稳定时间更短,能够更好的对水轮发电机组进行在线控制。
Research on water turbine generator optimal control problem.The electric power voltage and frequency should maintain the stable value to ensure safety power supply.Water turbine generators is a nonlinear and time-varying complexity system and the traditional PID control algorithm is difficult for accurate controlling,which causes a long stabilizing time for the system.To solve the above problems,the paper proposes a water turbine generator control method based on CMAC and PID.Using CMAC feed-forward control,the control method speeds up the system response speed and reduces the overshoots,thus enhances the control accuracy.PID is used to realiz feedback control and ensure that the system is stable and the system disturbances are reduced.Simulation results show that the compound CMAC and PID controller,compared with the conventional PID controller,is more smooth and faster in adjusting,and improves the real-time performance,and enhances the stability of the system,which ensures better control effects.
