摘要
In this paper, a large-signal non-ideal averaged model of DC-DC boost converter for continuous conduction mode is developed and implemented using MATLAB s-function, which is used to perform nonlinear simulation. In addition, a new pulse-width modulated based proportional-integral sliding-mode current controller with a constant ramp voltage is introduced. The nonlinear controller eliminates the steady-state error, maintains constant switching frequency, and tracks the desired reference signal under large line and load disturbances. The simulation is conducted in MATLAB/SIMULINK to validate the control design methodology. The simulation results show that the proposed controller provides good tracking and regulation performance with a wide operating range.
