摘要:
为取得系统对负载和参数扰动的高稳定性,同时避免滑模控制( SMC) 具有的抖振现象,将 一种新的滑模变结构控制策略应用于永磁同步电机( PMSM) 驱动系统中。采用最大转矩电流比 ( MTPA) 控制分配定子 d、q 轴电流,并将它们与转矩的关系拟合为低阶多项式,有效地提高了该方 法的工程实用性; 阐述了在系统存在性条件下改进的变指数趋近律控制策略,通过恰当地选取积分 滑模面和切换增益,并将控制律连续化,有效地削弱了滑模控制方法的抖振问题。仿真与实验结果 表明,该方法可以有效抑制系统抖振,改善系统鲁棒性,同时具有良好的动、静态性能。
Abstract:
To achieve high stability of system to the parameters and load disturbances,while avoiding slid-ing mode control ( SMC) chattering,a new variable structure control policy was introduced into a perma-nent magnet synchronous motor ( PMSM) drive system. By using maximum torque per ampere control to distribute stator d,q-axis currents,and fitting their relationship with the torque for low-order polynomials, the engineering practicability of MTPA method was improved; the variable exponential reaching law con-trol strategy was analyzed under the existence conditions set forth in the system,by properly selecting switch gain and integral sliding surface,realizing continuous control law,and the chattering problem was effectively weakened in the SMC system. Simulation and experimental results show that this method effec-tively suppresses system chattering,improves system robustness,and also is of good dynamic and static performance.
