Description
The Servo Trainer shows DC servo position and speed control systems using typical industrial techniques. It has a DC servomotor, a DC generator and a flywheel mounted on a common shaft. Analogue 0 to ±10 V control signals vary the servomotor shaft speed in either direction. An optical sensor measures the speed and shows it on a panel-mounted digital meter. The DC generator statically or dynamically loads the servomotor. An electric clutch connects or disconnects the shaft to a 30:1 reduction gearbox for position control studies. A manual control allows the user to set a position control setpoint. To adjust the shaft inertia, the comes with two extra interchangeable inertia discs (flywheels). For advanced experiments, the Servo Trainer includes extra ‘block’-type circuits that can add non-linear and fully adjustable effects of:
Deadzone or ‘deadband’
Anti-deadzone
Hysteresis
Saturation
These blocks are important in studies of servo systems because they mimic problems that happen in real applications.
Learning Outcomes
Basic tests and transducer calibration
Response calculation and measurement
Proportional and proportional plus integral control of servo-system speed
Disturbance cancelling and feedforward control
Angular position control: proportional control and velocity feedback
Angular position control and the influence of nonlinearities
Non-linear system characteristics
The flexible design of the equipment allows the user to develop many other analysis and control exercises to suit their needs. It is good for extended or advanced control experiments, and is ideal for student project work.
