Pure Liquids and Commercial Liquids: Pure liquids are those which are chemically pure and do not contain any other impurity even in traces of 1 in I09, and are structurally…
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…
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…
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.…
Correlation Between Frequency and Transient Response: As has been stated, the use of frequency response for the design of control systems requires a Correlation Between Frequency and Transient Response. Time…
Three Phase Drives: Single phase drives discussed in the previous section are employed for low and medium powers. When the power of the drive is very large the three-phase converter…
Current Source Inverter Fed Induction Motor Drive: Current Source Inverter Fed Induction Motor Drive - In a voltage source inverter fed induction motor the applied voltage to the stator is…
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.…
