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…
Stability from Bode Plot of Open Loop Transfer Function: The Nyquist criterion details how the open loop polar plot can be used for establishing. the stability of a closed loop…
Frequency Response Transfer Function: The previous sections- show that with the time response of a system, even though it is a direct method of analysis, the adjustment of the parameters…
Ward Leonard Drive Transfer Function: In the classical Ward Leonard Drive Transfer Function, the dc drive motor having constant excitation is supplied from a variable voltage generator, as shown in…
Transfer Function of a Field Controlled DC Motor: The speed of a dc motor can be varied by varying the field current. The speed can be increased beyond base speed…
Time Delay Circuit: Several choices are available in the selection of suitable circuits for obtaining Time Delay Circuit depending on the magnitude of the time delay required. Delays of the…
Step Function Response: The step function response consists of applying an instantaneous change in the control means and then recording graphically the result of the change on the measured variable.…
