Field Oriented Control of Three Phase Induction Motor: The stator current of an induction motor has the functions of producing the required air gap flux (magnetisation) as well as developing…
Control of DC Drives Using Microprocessors: The dc motors fed from thyristor converters for variable speeds are being extensively used in general industrial applications. A dual converter, which is a…
Function Generation and Linearisation: An important aspect of the closed loop control system is the use of Function Generation and Linearisation, e.g. in the control of induction motors there exists…
Symmetrical Optimum: Symmetrical Optimum - Sometimes automatic control systems contain integrating also besides first order delay elements, proportional elements and deadzones. Such a system when compensated on the basis of magnitude…
Uncompensated Large Time Constants: It is possible to compensate only one Uncompensated Large Time Constants using a PI controller. A PID controller is used to compensate for two large time…
Controller Transfer Function: While a Controller Transfer Function is designed to improve the behavior of a given control system in practice it is very difficult to realize such a controller…
Phase Margin Optimum: The method can be based on the phase margin in which the controller is designed to provide a minimum phase margin. The design makes use of Bode…
Magnitude Optimum: The design of a controller based on the principle Magnitude Optimum that it allows all the frequencies to pass through in a similar way for a simple system is…
