Abstract

A novel feedback control scheme for speed regulation of permanent magnet synchronous motor (PMSM) is presented based on energy-shaping and port-controlled Hamiltonian (PCH) systems theory. The desired state error port-controlled Hamiltonian structure is assigned to the closed-loop PMSM system by feedback control. Using interconnection and damping assignment passivity-based control (IDA-PBC) methodology, speed controllers are designed when the load torque is known and unknown, respectively. The stability of the desired equilibrium point satisfying the maximum torque per ampere (MTPA) control rule is also analysed. Proportional integral (PI) control of speed error is used to estimate the unknown load torque. At last, the speed controller is implemented based on space vector pulse-width modulation (SVPWM) control rule. By controlling every inverter switch, three-phase PWM voltages satisfying the speed regulation requirement are provided to the stator windings of PMSM. The good dynamic and steady-state performances of the presented scheme are verified by simulation results.

基于端口控制哈密顿系统和PI控制原理的永磁同步电机调速

提出了一种基于能量整形和端口控制哈密顿(PCH)系统理论的永磁同步电机调速反馈控制方案。通过反馈控制将理想状态误差分配给闭环永磁同步电机系统。采用互连和阻尼分配无源控制(IDA-PBC)方法，分别在负载转矩已知和未知时设计了速度控制器。分析了满足最大转矩/安培(MTPA)控制规则的理想平衡点的稳定性。采用速度误差的比例积分控制来估计未知负载转矩。最后，基于空间矢量脉宽调制(SVPWM)控制规则实现了速度控制器。通过控制各逆变器开关，为永磁同步电机定子绕组提供满足调速要求的三相PWM电压。仿真结果验证了该方案具有良好的动态和稳态性能。
