This experimental unit forms part of a series of teaching systems developed in collaboration with the Department of Automation and Information Technology at the Harz University of Applied Studies and Research. A fuzzy control is used to move the ball to a specific position quickly and with as little movement of the plate as possible, even when the position of the ball is modified by external influences. A ball-plate model acts as a weakly-coupled mechanical multivariable system. The inclination of the plate is modified by the movements of the respective motors; these movements are transferred to the plate by the drive rod. A joystick can be used to control the system manually. This allows the degree of difficulty of the control process to be estimated very accurately. The position of the ball is measured without feedback using a touch panel and the crisp signals sent to the fuzzy controller, where the signals are transformed into fuzzy input values and inferenced before being transformed back into a crisp output value. Two servo motors act as actuators during this process.

The tension of four different rotational speed sensor
The characteristics of the tension from the sensors depending on the gap width for the specified rotation speed
The characteristics of the tension from the sensors depending on the rotational speed of the toothed ring.
The pressure value in the hydraulic circuits (in the brake master cylinder or after a correction made by the ABS/ASR system)
The depth of the amplitude modulation of the sensors signal being a result of the whipping of the toothed ring in the function of the gap width.
The controller can operate as a configurable PID controller and as a 2-point controller. In the latter case, as well as the setting of the reference variable, the hysteresis can also be pre-set. The recorder function provides continuous recording of controlled, manipulating and reference variables. The software ideally supports the experimentation and learning process of demonstration models. Its key features are the software controller and the recorder function. It plots responses to changes in the reference (e.g. step input) and disturbance variables. The controller included with each demonstration unit can also be used instead of the software controller. Measured values can be printed out and saved to data media. Connection to a PC is by a USB port. The supplied USB interface module provides an adequate number of analogue inputs and outputs, enabling even complex circuits, such as a cascade to be controlled. In this case, controlled, manipulating and reference variables can be plotted, displayed and saved by the program's recorder function.

The operation of these level sensing devices can readily be investigated since they may be removed from the Demonstration Unit, dismantled and re-assembled, without the attendant problems which would occur on an operational boiler. The simulated boiler itself is constructed from a clear acrylic tank and thus the demonstration unit provides a clear visual appreciation of the operating characteristics of the various level controls i.e. float operated magnetic, reed or electronic system using electrode sensors. An arrangement of up to date integrated circuits is used to simulate boiler pressure and burner control together with the sensing and control systems associated with modern boiler systems. A Boiler Water Gauge is fitted to the Boiler Drum so that possible misuse of this item can be demonstrated clearly and safely. This Gauge can also be used to demonstrate the method of changing a sight glass for such a gauge under simulated working conditions, a circumstance which can be safely taught on this Demonstration Unit. These systems would not normally all be fitted in the same boiler but are included in this unit to give the student an appreciation of the characteristics of each system. Conversion of water from the boiler into steam is simulated so that the level sensors need to operate as in a true Boiler system.

The water finally flows back into the sump tank T1, the heat introduced into the system being removed by a water cooler, HE1. V2 simulates a vessel used for a hazardous process reaction, demanding the use of flame proof control equipment in its immediate vicinity, thus providing a logical reason for the use of pneumatic and interfaced control equipment. The process which forms the basis of operation of the various control loops and equipment is illustrated in. Water is fed to a centrifugal pump from sump tank T1 and then to a water heater HE2 before passing into two vessels V1 and V2, mounted in series and simulating a reactor system. Four standard areas of control are presented.
