The DC motor is a key element for servo system, and the control quality of control system would be seriously affected by the nonlinear, the parameter uncertain, the inaccurately modeling and some uncertain existing in servo system. So it is very difficult to satisfy control requirements by using the traditional control method. In this paper, the sliding mode control algorithm with reaching law is proposed. By using the reaching law to weaken the chattering phenomenon existed in the SMC, also by using the SMC method can enhance the anti-interference ability of the servo system. In order to test and verify the effectiveness of the proposed SMC with reaching law for the DC motor, the designed controller was dynamically simulated by using the MATLAB. It is shown from the simulation results that the proposed controller offers several advantages such as good chattering inhibition capability, fast response, good disturbance rejection capability, good position tracking capability and so forth. It is also revealed that the proposed control strategy is valid for the DC servo system from simulation results. The results also provide the certain theoretical basis and application value for engineering practice.
