Abstract

This paper represents a robust nonlinear control strategy to solve the instability problem of dc-dc boost power converter with constant power load by using double integral sliding mode control (DISMC) method. DISM is an indirect type of sliding mode control strategy and overcomes the problems due to CPL. DISM provides better tracking performance of voltage and eliminates voltage steady state error. This strategy ensures large signal stability as well as fast recovery performance as compared to other control methods. To show the effectiveness of the DISM in overcoming instability issues of the CPL in boost converter a 24 to 48 V converter is designed, and MATLAB simulation performed.
