摘　　要：为了优化提升机在不确定负荷条件下的运行状态,利用模糊控制器和PID控制器设计了一种双闭环串级控制系统。以冗余S7-1500R PLC和SL150变频器为硬件核心,利用模糊控制器给出平衡负荷的转速值,再通过PID控制器优化提升机工作。系统采用冗余PLC架构,既能提高提升机工作的可靠性,又能降低能耗,满足不确定负荷控制要求。In order to optimize the operation of hoist under uncertain load conditions,a double closed-loop cascade control system is designed with fuzzy controller and PID controller.Using a redundant S7-1500R PLC and SL150 inverter as the hardware core,the fuzzy controller is used to give the speed value for balancing the load,and then the PID controller is used to optimize the hoist operation.The system uses a redundant PLC architecture to improve the reliability of hoist operation and reduce energy consumption to meet uncertain load control requirements.
