基于模糊迭代控制的SRG输出电压脉动抑制
|
摘要
针对开关磁阻发电机换相期间导致输出电压脉动问题,分析了发电机原理,采用电流分配方法,将期望电流分配至各相绕组,则换相重叠区两相电流可互相补偿,减小电流波动。研究基于模糊迭代控制算法的电流控制策略,相比迭代电流控制,可进一步提高电流收敛速度和跟踪精度,同时减小了输出电压稳态误差,从而实现输出电压的优化。仿真分析和样机实验表明,该控制策略能有效抑制输出电压脉动,减小稳态误差。
The problem for the fluctuation of the output voltage during commutation of the switched reluctance generator( SRG) was discussed,Aiming at the reason,the principle of generator was analyzed. The current distribution method was used to allocate the specified current to each phase winding and the current in the commutation interval compensated each other and reduced current fluctuation. And the current control strategy based on fuzzy iterative control algorithm was introduced and can further improve the current convergence speed and tracking accuracy and while reduce the output voltage steady-state error compared to the iterative current control,thereby achieve the output voltage optimization. Simulation analysis and prototype test show that the control strategy can effectively suppress the output voltage fluctuation and reduce steady state error.
