This paper designs a simulation experiment platform of boost circuit controlled by PIC single chip microcomputer based on Proteus simulation software.The simulation platform is composed of boost circuit and MCU control system software and hardware.Through hardware circuit and program design,the constant voltage or constant current control of boost circuit is mainly realized.Based on the research of linear incremental algorithm and PID control algorithm,the control effects of the two algorithms are compared and analyzed on the simulation experimental platform.The results show that both algorithms can realize the boost constant voltage output of boost circuit.The linear increment algorithm is simple and easy to understand,but the overshoot is large and the control speed is slow.The PID control method has fast control speed,but the process of parameter setting is complex.
