PSO Based Adaptive Terminal Sliding Mode Controllers for a DC-DC Converter

H. Abderrezek and M. N. Harmas
Abstract—This paper presents an adaptive non-singular terminal sliding mode (ANTSM) tracking control design for DC-DC buck converter. An adaptive Terminal sliding mode control method is presented for nonlinear systems with parameter uncertainty and external disturbance. The method estimates the boundary of parameter uncertainty and external disturbance by adaptive law. The idea behind this strategy is to use the terminal sliding mode control (TSMC) approach to assure finite time convergence of the output voltage error to the equilibrium point and integrate an adaptive law to the TSMC strategy so as to achieve a dynamic sliding line during the load variations. The convergence rate is fast, and a strong robustness can be achieved. Control parameters are optimized using a Particles Swarm Optimization (PSO) algorithm to further enhance performances.

Index Terms—DC-DC converter, sliding-mode (SM) control, terminal sliding mode controller (TSMC), adaptive, PSO.
