General purpose process control unit

Abstract

The main purpose of the thesis is to make a control unit where different models can be tested with a number of motors, sensors, indicators, control devices which are used by Fischertechnik in training models. This work observes different types of speed motor control and investigates most useful method that could be implemented at the PLC Lab. It would be very useful to simulate separated parts of the unit by using different software and compare actual results with theoretically expected results. All the results must be realistic and simply implemented in a real lab. Obtained circuit should be implemented in board layout after succeed simulations and checked for safety using in future. Measured signal, voltage level on each node and behavior of motors should be similar to the theoretical results
