This report presents a new way of control engineering. Dc motor speed controlled by three controllers PID, pole placement and Fuzzy controller and discusses the advantages and disadvantages of each controller for different conditions under loaded and unloaded scenarios using software Matlab. The brushless series wound Dc motor is very popular in industrial application and control systems because of the high torque density, high efficiency and small size.

These sensors original are used to detect the position of rotor, so the resolution is very low and the speed sampling time intervals depend on rotor speed. Due to the variation of speed, the time intervals are also unfixed. This thesis proposes a controller with speed control and torque compensation. Under different speed range, the traditional proportional-integral controller is not suitable in variable sampling system. According rotation speed, the thesis proposes a mini

The SRM are known having the advantage of large torque, high power density, high efficiency, no rotor windings and low cost, so that it is suitable for wide using in industries. However, the inevitable high nonlinearities are caused by the structure of salient poles of SRM on both rotor and stator, so that the excellent control of such system is difficult to

Results of simulation and experiment validate the performances of the proposed controller. The V/f control is a conventional method for controlling an induction motor speed since the construction is simple and the motor parameters are not required. However, this method uses a constant ratio of the voltage to the frequency, which is effective under steady state only. The speed

The adoption of the subject controller can improve the system's dynamic response. In conventional grey prediction controller, the prediction step size is fixed, an excessive step size implies longer settling time. On the contrast, insufficient step size causes fast response with larger overshoot. For improvement, based on the error and its change of the system’s response, a fuzzy-inference mechanism is used to obtain proper grey prediction step size. Com
