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.
