PID控制广泛应用于工业过程控制中,但由于传统PID控制在控制精度,响应速度等方面存在缺点和不足,本文提出了一种模糊自适应PID控制,该控制方法由于其能够自适应的调整比例(kp),积分(ki),微分(kd)的作用,使得工业控制系统的稳态性能得到增强,响应时间变短,自适应能力得到增强。本文应用Matlab仿真软件中的Simulink工具箱对模糊自适应PID控制及传统PID控制系统进行了仿真,仿真结果表明,模糊自适应PID在性能上优于广泛应用的传统PID控制。
PID control is widely used in industrial process control, but due to the shortcomings and shortcomings of traditional PID control in control accuracy, response speed, etc., this paper presents a fuzzy adaptive PID control, the control method due to its adaptive scaling (kp), integral (ki) and derivative (kd), the steady state performance of industrial control system is enhanced, the response time is shortened and the adaptive capacity is enhanced. In this paper, Simulink toolbox in Matlab simulation software is used to simulate fuzzy adaptive PID control and traditional PID control system. The simulation results show that the fuzzy adaptive PID is superior to the widely used traditional PID control in performance.
