在感应电机IM(Induction Motor)的控制中,电阻、电抗等参数对转速控制产生较大的误差影响,从而影响控制精度和动态响应速度。基于感应电机的数学模型,将模糊逻辑系统引入预测控制。针对异步电机的强耦合特性,提出模糊模糊预测控制的方法,并用模糊预测控制的方法设计了高性能的转速控制器。并借助DSP实验平台,将系统模型下载到实时硬件中进行在线仿真,实验结果表明,所设计的控制器在提高速度控制的快速性和抗干扰能力上得到满意的效果。
In the induction motor IM (Induction Motor) control, resistance, reactance and other parameters on the speed control has a greater error, thus affecting the control accuracy and dynamic response speed. Based on the mathematical model of induction motor, fuzzy logic system is introduced into predictive control. Aiming at the strong coupling characteristic of asynchronous motor, a method of fuzzy fuzzy predictive control is proposed, and a high performance speed controller is designed by fuzzy predictive control. The system simulation model was downloaded to the real-time hardware for on-line simulation with DSP experiment platform. The experimental results show that the designed controller is satisfactory in improving the speed control and anti-interference ability of speed control.
