The apparatus has two transparent tanks, mounted one above the other. A variable-speed pump transfers water from the reservoir (in the base of the unit) into the upper tank. PLC Process gives students and engineers practical experience of the principles and application of programmable logic controllers (PLCs). The object is to connect and program an external, programmable logic controller to monitor and control the level and flow rate of water in a two-tank system. The pump control is on or off, but a manual control allows the user to set the speed. A float switch in the reservoir monitors the level of water. The water can drain down to the lower tank and then back into the reservoir. Solenoid valves may be individually opened or closed to control and redirect the movement of the water.

The basic control task is to control the vertical position of the freely levitating ball in the magnetic field of the coil. The Magnetic Levitation Apparatus is a non-linear, dynamic system with one input and one output. The Magnetic Levitation Apparatus shows control problems with non-linear, unstable systems. The apparatus consists of a steel ball held in a magnetic field produced by a current-carrying coil. Any imbalance and the ball will move away from the set-point position. A sensor measures the position of the ball. At equilibrium, the downward force on the ball due to gravity is balanced by the upward magnetic force of attraction of the ball towards the coil. A power amplifier with overheat protection drives the coil.

Process Trainer is an educational package that mimics industrial process engineering. The fully integrated, selfcontained teaching apparatus gives a comprehensive range of process control experiments, from basic to advanced. Using water as the working fluid, the equipment allows safe, practical experiments on control of flow, liquid level, temperature and pressure. Students can study each of these separately or in combinations.

The Ball and Plate Apparatus shows the problems of the of an unstable system. The apparatus consists of a plate pivoted at its centre so the plate can tilt in two directions.
The basic control task is to control the ball position. The ball is free to roll on the plate.
Stepper motors tilt the plate. A servo system with a stepper motor control card controls the motors. A camera with an intelligent vision system measures the ball position.
The equipment includes:
A data acquisition board for your computer
Camera with USB connection
Ball and plate model
Power supply
The data acquisition board fits into a suitable computer (not included) to link with the Ball and Plate Apparatus and control its motors.
Software (included)
Interface library for programming at the system level
Demonstration program with PID controllers
The model simulates a helicopter with horizontal and tail rotors to give pitch and yaw control. The control system must keep the helicopter stable and allow for a change in the centre of gravity. When operating near the steady state, the electromechanical system can be linearized to a six-order model. Sensors measure the yaw and pitch angles. This gives a two-input and two output system, with cross-coupling. Students use the educational manual (supplied) to help identify plant dynamics and create a control system.
The equipment includes:
The model helicopter on a stand
A protective steel cage to put around the helicopter for safety
An interface unit
A data acquisition board for your computer.
