摘要 机械弹性储能系统在储能过程中驱动电机负载的转矩和转动惯量连续变化,情况复杂,需要一种能够快速跟踪其变化且抗干扰能力较强的控制系统。直接转矩控制响应快,能快速跟踪储能箱转矩,结合反推自适应控制算法,可以使其有较好的稳态和暂态性能。首先采用遗忘因子递推最小二乘算法辨识储能箱转矩和转动惯量,实时更新控制对象参数,结合辨识结果设计转角、转速、转矩和磁链反推控制器,并最终得到定子电压在两相静止坐标系下的分量,同时设计转矩和转动惯量自适应控制器消除辨识误差对控制性能的影响,进一步应用电压空间矢量调制方法产生频率恒定的开关信号,控制逆变器运行。实验结果表明永磁同步电机输出转矩能够快速跟踪负载转矩,且转矩转速脉动较小,储能过程平稳。

Abstract:Torque and moment of inertia of the permanent magnet synchronous motor (PMSM) load is simultaneous continuously changing in the process of energy storage in mechanical elastic energy storage (MEES) system. A kind of control system which can track the change quickly and has strong anti-jamming ability is needed under this circumstance. Combining backstepping adaptive control algorithm with direct torque control (DTC) system with the feature of fast-speed response and easy to track control target, which has good steady and transient performance. A single recursive least square (RLS) estimation algorithm with forgetting factor is designed to simultaneously estimate load torque and inertia in this passage firstly, furthermore, an backstepping controller of the rotation angle, speed, torque and flux linkage was designed and finally get the stator voltage in the two-phase stationary coordinate system. At the same time, an adaptive algorithm was added to eliminate the identification error, then the space vector modulation method was applied to generate the switching signals to control the operation of the inverter. Experiment results indicate that the output torque of PMSM can quickly track the load torque, the torque ripples are low, and the energy storage process is stable.
