摘要
为了解决直流电机作为动力驱动升降平台时,由于机械加工精度和电机一致性,产生的非线性阻力所导致的同步性能差、定位精度低、速度难以控制等问题。提出并基于FPGA设计了模糊PID控制器来控制直流电机的速度,通过对平台速度误差e与误差变化量ec的闭环控制,采用模糊推理机制,实现了非线性阻力的自适应控制。通过对各个模块联合仿真结果可知,该模糊PID控制器能够满足控制要求。
In order to solve the problems of poor synchronous performance,low positioning accuracy and difficult to control speed caused by the non-linear resistance caused by the machining accuracy and motor consistency when DC motor is used as the power driven lifting platform.In this paper,a fuzzy PID controller is proposed and designed based on FPGA to control the speed of DC motor.Through the closed-loop control of platform speed error E and error rate of change EC,the fuzzy reasoning mechanism is adopted to realize the adaptive control of nonlinear resistance.According to the simulation results of each module,the fuzzy PID controller can meet the control requirements.
