A Nonlinear Servo Control Method Based on Integral Backstepping Scheme

External disturbances and system parameter changes will reduce the function of a mechanical servo control system and even bring instability to the system. This paper presents a new servo controller which is based on integral backstepping scheme. The controller has strong robustness towards external disturbances and system parameter changes. The results of the simulation of a DC motor servo system indicate the effectiveness of the proposed method.
