Exponential Variation of the Input to the Controller: The linear Exponential Variation of the input to the Controller, discussed in the foregoing section, is too involved to achieve by means…
Methods of Compensation in Control System: The Different Methods of Compensation in Control System are Cascade Compensation Feedback Compensation Load Circuit Compensation Input Circuit Compensation A drive system having closed…
Control System Performance: From the foregoing discussion on control systems it can be seen that the behaviour of the control systems can be specified, based on several time domain specifications.…
Root Locus Plot: In the electrical drives employing closed loop control techniques, it is often necessary to investigate the effects of changing the parameters of the system on its stability.…
Relative Stability from the Nyquist Plot: Relative Stability from the Nyquist Plot - The considerations discussed above provide information about the absolute stability of the system, i.e., whether the system…
Stability Control Drives: The concept of stability is very well known. By the term stability one implies the ability of a system to return to its original position or attain…
Methods to Leading Power Factor: We have seen that a phase controlled converter requires reactive power for control and commutation. The harmonics do not contribute to the active power loading…
PWM Inverter Fed Induction Motor Drive: Voltage control in the square wave inverter has been external to the inverter, by means of a phase controlled rectifier on the line side.…
