High speed activation and stopping control system using the bang-bang control for a DC motor

In this paper, we propose a high speed activation and stopping control system using the bang-bang control for a dc motor. The Bang-Bang control is able to control the actuator in high speed activation and stopping. However, when there are torque disturbances in actuators, the target-position is not able to be precisely stopped. Therefore, we design the switching control system. It operates from the bang-bang control to PID control continuously. Here, the system includes various factors to consider designing. For example, calculating switching time of bang-bang input, and how to operate continuously from the bang-bang control to PID control, and so on. Theoretical analysis is described and how to design the proposed method in detail. In simulation studies, it shows results of various cases to indicate the effectiveness of our proposed method.
