Software should combine controller design & implementation into one logical process ? This should reduce learning difficulties and help quickly to understand & create a working control system ? User should be able use the software icons and wire them together on screen, just as they would draw a control system on a piece of paper ? The icons should include important parts of controllers, signal generators, manually controlled signals & voltages and virtual instruments ? The software can be used to record important variables ? Plotting the results in a chart and exporting data for use in other programs ? Students should be able to create one or more types of controller and simulate the theoretical responses ? The user guide should show users how to use the software and how to build and test common control systems, such as: ? Design and implementation of three-term controllers ? Design of controllers and filters ? Simulated signals: Signal generator (sinusoidal, saw tooth & square wave), with variable frequency, amplitude & offset and D.C. level (fully variable) ? Virtual instruments: Digital meter, Bar graph, Analogue meter, Oscilloscope and Chart recorder ? Controller blocks: Proportional gain, Integral gain, Derivative gain and Phase advance ? Simulation blocks: Integer, First order system, Double integrator, Second order system, First order with integrator system and Second order under damped system ? Other blocks: Gain, Voltage to frequency convertor, Delay, Discrete transfer, Saturation, Summing junction (three input), Multiplier (three input), Switch and Relay
