Abstract :
This paper presents an adaptive nonlinear position controller with velocity constraint, capable of combining the input-output linearization technique and Lyapunov stability theory. Based on the Lyapunov stability theory, the adaptation law of the proposed controller is derived along with the verification of the overall system´s stability. Computer simulation results demonstrate that the proposed controller is robust and it can ensure transient stability of SEDCM, under the occurrence of a large sudden fault
