摘要

当有限集模型预测控制(Finite Control Set Model Predictive Control

FCS-MPC) 应用在永磁同步电机(Permanent Magnet Synchronous Machine

PMSM) 弱磁控制时，系统存在参数鲁棒性较差的问题。为了解决此问题，本文提出一种基于比例−积分−微分(Proportional-Integral-Derivative

PID) 型代价函数的FCS-MPC永磁同步电机弱磁控制策略。在该策略中，PID型代价函数由3部分组成：跟踪电流的比例误差代价、削弱稳态控制误差的积分误差代价和降低纹波误差的微分误差代价。本文依据永磁同步电机的数学模型建立了预测模型，详细描述了PID型代价函数的FCS-MPC在永磁同步电机弱磁控制中的实现过程。同时，为了保证预测的准确性，对系统采用了延时补偿策略。仿真结果证明，当永磁同步电机在弱磁控制中参数失配时，本文提出的基于PID型代价函数的FCS-MPC，不仅可提高控制系统对电机参数和负载转矩扰动的鲁棒性，还保留了FCS-MPC良好的动态性能。

Abstract

When finite control set model predictive control (FCS-MPC) is applied in the flux-weakening control of permanent magnet synchronous machine (PMSM)

the system suffers from poor parameter robustness. To solve this problem

a proportional-integral-derivative (PID) -type cost function of FCS-MPC in the flux-weakening control of PMSM is proposed. In the proposed strategy

the PID-type cost function consists of three components: the proportional error cost of tracking the current

the integral error cost of weakening the steady-state control error

and the differential error cost of reducing the ripple error. The prediction model is established by the mathematical model of PMSM

and the implementation process of FCS-MPC with PID-type cost function in the flux-weakening control of PMSM is described in detail. Meanwhile

the delay compensation strategy is applied to the system to ensure the accuracy of the prediction. The simulation results prove that when the parameters of the PMSM are mismatched in the flux-weakening control

the FCS-MPC base on the PID-type cost function can not only improve the robustness of the control system to motor parameters and load torque perturbations

but also retain the good dynamic performance of FCS-MPC.
