Abstract

A nonlinear hybrid control approach is proposed in this paper to control the speed of a DC-DC buck converter driven DC motor. An adaptive backstepping sliding mode control theory is used to design the proposed controller. To handle the sudden load variation effects, the load torque is considered as unknown terms which will be estimated using an adaptation law. The theoretical stability of the system is ensured by using the Lyapunov theory. Finally, a simulation study is conducted to demonstrate the effectiveness of the proposed control scheme, and the performance is compared with an existing controller. Simulation results reveal that the proposed controller outperforms the existing controller in terms of overshoot and settling time.
