电梯的速度控制具有非线性和大滞后等特点,很难建立精确的数学模型。本文为此设计了一种模糊PID控制算法,并利用MATLAB软件进行仿真分析。结果表明,模糊PID控制器和传统PID控制器相比,动态响应快,无超调现象,具有较好的鲁棒性,可以使曳引式电梯实现调速过程的平稳控制。 Elevator speed control with nonlinear and large lag and other characteristics, it is difficult to establish an accurate mathematical model. In this paper, a fuzzy PID control algorithm is designed and simulated by MATLAB software. The results show that compared with the traditional PID controller, the fuzzy PID controller has the advantages of fast dynamic response and no overshoot. It has better robustness and can make the hoist elevator realize the smooth control of the speed regulation process.
