摘　　要：将终端滑模控制应用于Boost变换器中,建立了Boost变换器状态空间平均法模型。引入了指数控制律以提高系统的响应速度,改善Boost变换器的动态性能,设计了负载观测器以增强系统对负载干扰的鲁棒性。仿真结果表明,所提控制策略对输入电压和负载电阻的变化具有良好的动态响应,系统控制响应速度快、鲁棒性好。Terminal sliding mode control is applied to Boost converters,and a Boost converter state space averaging model is estab-lished.An exponential control law is introduced to enhance the system's response speed and improve the dynamic performance of the Boost converter.A load observer is designed to increase the system's robustness against load disturbance.The simulation re-sults demonstrate that the proposed control strategy has good dynamic response to changes in input voltage and load resistance,with fast system control response and good control robustness.
