一种基于MFAC策略的异步电机电流控制器

An Asynchronous Motor Current Controller Based on Model-free Adaptive Control Strategy

由于异步电机是一个多变量强耦合非线性系统,传统的控制方法对受控电机参数较为敏感、鲁棒性不足。而无模型自适应控制策略作为一种数据驱动控制策略,只需要被控对象的实时输入输出数据即可实现高水平控制。本文设计了一种基于无模型自适应控制策略的异步电机电流控制器,仿真和实验表明,基于无模型自适应控制方法设计的异步电机电流控制器具备可行性与良好的鲁棒性,且相比于传统的电流控制策略性能更加优越。

Due to the fact that the asynchronous motor control system is a multivariable strongly coupled nonlinear system,traditional control methods suffer from sensitivity to the parameters of the controlled motor and insufficient robustness.As a data-driven control strategy,model-free adaptive control only requires the real-time input and output data of the controlled object to achieve high-level control.This article designed an asynchronous motor current controller based on MFAC strategy.Simulation and experiment show that the asynchronous motor current controller designed based on model-free adaptive control strategy is feasible,and has robustness and performs better compared to traditional current control strategies.
