中文摘要:
      为了克服传统串级调速功率因数低及能量损耗大等固有缺点,提出了一种基于逆系统解耦附加变结构控制的电流型PWM串级调速系统。为增强系统的鲁棒性,PWM逆变器选用逆系统解耦附加变结构控制策略,并对该控制策略进行详细推导,加之斩波电路选用转速电流双闭环PI控制,最终获得了系统的控制图。最后利用MATLAB对该控制策略的有效性进行了仿真验证。仿真结果证实系统不仅具有良好动态特性,而且提高了功率因数,减少了谐波,节约了能源。
英文摘要:
      In order to overcome the inherent shortcomings of traditional cascade speed regulation such as low power factor and great energy loss, the current mode PWM cascade speed regulation system based on inverse system decoupling additional variable structure control was proposed..In order to enhance the robustness of the system, the inverse system decoupling additional variable structure control strategy was adopted in the PWM inverter, and the control strategy was deduced in detail. Combined with the speed and current double closed loop PI control adopted by the chopper circuit, the control chart of the system was obtained. Finally the effectiveness of the control strategy was simulated and verified by using Matlab. The results proved that the system not only had good dynamic performance, but also improved the power factor, reduced the harmonic and saved the energy.
