摘要
为抑制宽转速范围条件下柔性自激异步发电系统(FS-CAGS)电压定向谐波干扰,提高FS-CAGS鲁棒稳定控制能力,实现功率快速跟踪控制,采用扩展卡尔曼滤波EKF电压定向与反演自适应滑模控制相结合的方法,提出一种EKF电压定向反演自适应滑模直接功率控制新方法.军用底盘集成式直流微电网中FS-CAGS控制仿真实验结果表明,在负载冲击扰动和宽转速突变条件下,相对于传统直接电压定向精确反馈线性化鲁棒控制方法,新控制方法可加快直流输出电压稳定速度,减小电压超调,提高功率跟踪速度,FS-CAGS电流谐波抑制和鲁棒稳定能力得到加强.
In order to suppress the harmonic influence on the voltage orientation of flexible self-excitation cage asynchronous generation system(FS-CAGS),improve the stability control ability and realize the fast power tracking,with extended Kalman filter(EKF)voltage orientation and back-stepping adaptive sliding mode control method,a new EKF voltage oriented back-stepping adaptive sliding mode direct power control method is proposed.Simulation results of FS-CAGS in the military chassis integrated direct current(DC)micro-grid show,comparing with the traditional direct voltage oriented precision feedback linearized robust control method,under the condition of impulse load disturbance and the velocity mutation,the DC output voltage stable speed is fastened and overshoot is reduced,the power tracking speed is improved,current harmonics suppression and robust stability of the FS-CAGS are enhanced.
