摘要：
A simplified hysteresis sliding-mode control (SMC) is proposed to improve the dynamic response of the superbuck converter operating in continuous condition mode with high duty cycle values. The controller based on the sliding surface composed of output voltage error and input current error is derived and further simplified in structure. The simplified process decreases the number of control parameters and reduces system cost. The relationship between control parameters and the performance of the proposed controller is studied and verified by simulation. An experimental prototype using the proposed controller is designed with analog devices. Moreover, a dynamical performance comparison involving the proposed sliding-mode controller and existing controller is provided.
