Sliding Mode Backstepping Controller

In this paper sliding mode backstepping controller is proposed to extract maximum power from PV and to get desired grid voltage from battery of the PV battery system. The use of sliding surface in the backstepping procedure makes the error variable vanishes in quick time, which in turn the desired control law is obtained with enhanced transient and steady state responses. On basis of Lyapunov control function, control law obtained in order to obtain asymptotic stable system. The simulations are done for the wide range of variations at the input and output side. The obtained simulation results of the SMBS controller is compared with PID controller which shows that proposed controller outperforms PID controller in terms of transient and steady state response.
