Research on reversible speed regulation logic non-circulating current control system based on PLC

利用PLC的硬件和软件结构,实现逻辑无环流控制的转速及电流双闭环调速系统的设计。对传统的直流电机可逆调速逻辑无环流控制装置进行了改造,提高了直流可逆调速系统的可靠性、稳定性,并具备了快速性和抗干扰能力,且修改参数也方便灵活。实践运行调试验证了该系统具备上述优点。

With the configuration structure of software and hardware of PLC,the functions of logic non-circulating current switching and double closed-loop control of speed and current are realized.The traditional DC motor reversible speed regulation logic non-circulating current control device is reformed,which improves the reliability,stability,rapidity,anti-interference ability and flexibility of parameter modification of the DC reversible speed regulation system.The operation and debugging proves that the system can achieve the purpose of reversible non-circulating DC speed regulation.
