5.3: Feedback Compensation
You are to compensate the system to improve its phase margin to (60^{circ}) by reducing (a_0f_0) and by using lag and lead compensating techniques. You may not change the value of (C) or elements in the network connected to the output of the LM301A, nor load the network unreasonably to implement compensation.
How to Connect a Capacitor to a Single-Phase Motor
Three-Phase Motors: In three-phase motors, capacitors may be used to correct power factor or improve motor efficiency, but they are not as common as in single-phase motors. 6. Brushless DC (BLDC) Motors: Some BLDC motors employ capacitors for filtering and phase control to ensure smoother and more efficient operation.
