基于间接寻优的PMASynRM最大转矩电流比控制算法
PMASynRM Maximum Torque-Current Ratio Control Algorithm Based on Indirect Optimization
摘要
Abstract
The traditional FGAD-MTPA(Fixed-Gain Current Vector angle Detection Maximum Torque Per Am-pere)algorithm uses the partial derivative of torque as the self-increment of current vector angle search,which shows high sensitivity to the change of load conditions.In order to maintain the consistency of MTPA state convergence when the load changes,the MTPA algorithm of DV-AGAD(Double-Variable Adaptive Gain Current Vector Angle Detec-tion)is proposed.β-βMTPAis used as the self-increment of the vector angle to achieve the iteration of the optimal vec-tor angle.The SV-AGAD(Single-Variable Adaptive Gain Current Vector Angle Detection)algorithm is proposed,which can improve the dynamic convergence speed,reduce the complexity of the algorithm and the overshoot.Accord-ing to Lyapunov stability theory,the control system converges.The mathematical model of PMASynRM(Permanent Mag-net Auxiliary Synchronous Reluctance Motor)control system is established,and the SV-AGAD-MTPA algorithm is compared with the other algorithms.The results show that the new MTPA algorithm performs well under the conditions of acceleration and deceleration,loading and unloading,and reduces the sensitivity to parameters.关键词
