GBB series Ball & Beam control system are specially designed for courses in automatic control principle, modern control engineering, and electrical motor control. It is able to control the position of a stainless steel ball on the track by adjusting the rotating angle of a beam. The system consists of two parts, namely the Ball & Beam body and the control system. The Ball & Beam body consists of a v-grooved steel bar and a free rolling ball. The linear sensor measures the position of the ball on the track by measuring the output voltage from the stainless steel bar. A DC motor is connects to a gear reducer, which controls the angle of beam, accordingly realize the position control of the ball. Experiments such as system modeling, design of feedback controller, P, PD and PID control system design, design controllers using root locus methods, and frequency response methods etc. can be achieved with this experiment platform.
