• Coupled Drives apparatus shows the problems of controlling speed and tension in coupled drives. 
• A manual control allows the user to adjust the spring tension at the swinging arm. 
• The apparatus has two electric motors, coupled by a continuous flexible belt. 
• The belt also passes over a swinging arm with a ‘jockey wheel’ that measures the belt speed and tension. 
• The basic control problem is to vary the torque in the motors to regulate the belt speed and tension. 
• The user guide also shows techniques for speed and tension control, simultaneous control of velocity and tension, and analysis of multi-variable control systems.
• Many applications use coupled drives, for example: magnetic tape drives, textile machines and paper mills.

• Ball and Hoop Apparatus shows the use of electromechanical servo systems for position and velocity control. 
• The apparatus has a steel ball that rolls inside a hoop. 
• The hoop is free to rotate, but controlled by a servomotor. 
• Transducers give outputs of the hoop and ball positions. 
• When the hoop is under angular position control, the ball moves like a cylindrical pendulum. 
• This allows students to use it as a model for the study of liquid slop dynamics. 
• It also works as a model to show liquid slop problems, for example: aircraft missile fuel storage, fuel tankers and industrial pumping systems.

• Servo Trainer shows d.c. servo position and speed control systems using typical industrial techniques. 
• A manual control allows the user to set a position control setpoint. 
• The d.c. generator statically or dynamically loads the servomotor. 
• It has a d.c. servomotor, a d.c. 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. 
• An electric clutch connects or disconnects the shaft to a 30:1 reduction gearbox for position control studies. 
• To adjust the shaft inertia, 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
