What is Adaptive control system? If the process characteristics are not well known then what type of scheme you would suggest explain in detail the scheme and write its merits and demerits.

The armature circuit of a free excited direct current motor with a nominal voltage of 600 V is fed from an adjusted direct voltage source. The excitation circuit is also powered from a regulated voltage source. It is used in an application that requires motor speed adjustment. The speed of the motor at the nominal armature voltage was measured as 1600 rpm. All losses of the motor and voltage source and the effect of armature reaction are neglected. It is accepted that the engine is not saturated.Answer the questions below.a) Draw the armature and excitation circuit of the motor and write the formulas for the equivalent circuit.b) If the load moment of the motor at the nominal armature voltage is 420 Nm, then calculate the armature current and the input power of the motor.c) If the armature voltage of the motor is kept constant at 600 V and the excitation current is decreased until the speed reaches 4000 rpm, then calculate the shaft moment. Show this working area on the M = f (W) axis.

A 240 V, 50Hz single phase supply feeds a SP-FC-FWR. The rectifier is used to power the armature of a separately excited DC motor. The DC motor ratings are 220 V, 10 A (armature current), 940 rpm, Ra= 1.750. What is the no-load speed of the motor?

For the circuit in the figure below, the supply is 220 Vms, 60 Hz. The load resistance is 16 N. Neglect the Vr of the SCR. a) How much power is delivered to the load if the firing delay angle= 0°? b) How much power is delivered to the load if the firing delay angle= 90°? c) If the firing delay angle= 135°, will the load power be less than one-half or more than one-half of the amount delivered for a 90° delay angle? Explain. RLoad R1 R2 Vsupply SCR
