中文摘要:

由于三相电压型PWM整流器(VSR)采用传统PI控制策略难以在较大扰动和控制对象变化的情况下获得良好的调节效果,论文在传统的双闭环控制策略基础上,将PI控制与模糊控制相结合应用于电压外环控制,并将负载电流作为其前馈补偿,电流内环采用准PR(比例谐振)控制策略,为此提出了一种新型双闭环复合控制方法。通过MATLAB／Simulink仿真,结果表明了系统不仅有优良的动稳态性能,而且对外界扰动具有很强的鲁棒性。验证了该种控制方案的可行性。

英文摘要:

Since three-phase voltage source PWM rectifier (VSR) using conventional PI control strategy is difficult to obtain good regulation results in the case of large disturbances and changes of the control object, based on the traditional double closed loop control strategy, this paper makes the combination with PI control and fuzzy control, applied to the outer voltage control, and takes load current as feed-forward compensation, the inner current control loop uses quasi-PR (proportional resonance) control strategy. Thus, a new type of double-loop complex control method is proposed. The control system is simulated by MATLAB／Simulink,the results show that the system not only has excellent dynamic and steady state performance, but also has a strong robustness to the external disturbance,which verifies the feasibility of the scheme.
