A new control method for position control of DC servo motor based on the concept of variable structure control with sliding modes is presented.
The Conventional adaptive model following control with variable structure have a large chattering in the transient response.
In the proposed position controller, linear feedback control is added to the nonlinear control input in order to reduce the chattering phenomena in the transient response and to improve the dynamic response.
The performance of the proposed controller is compared with that of the conventional adaptive model following control with variable structure, and is verified using digital computer simulation and experiment.
