This paper presents the results of the analysis and synthesis of the control law for the tracking drive system using a synchronous motor and its accompanying power amplifier. Considering the synchronous motor and the power amplifier as one object, the sliding mode control law with the constant speed of approaching the sliding surface is added the exponent component, has created the anti-disturbance torque control signal considering the lower bound and upper bound of disturbance. The process of synthesizing control law is guaranteed mathematically based on Lyapunov stability. The simulation in Matlab shows visually the research results.
