i) Calculate the eigenvalues of a 100 hp, 1150 rpm dc machine at rated flux with no extra load inertia. Use the "hot" value of the armature resistance. Calculate estimates of the resulting speed overshoot and settling time (within 2%) for a step armature voltage input, beginning at an initial current of 0.
ii) Now assume that a closed-loop current regulator is introduced as shown in Fig. 2.7-3 of the book. What are the new eigenvalues of the motor-plus-regulator system if the current regulator gain Ki is set to 10? Ignore the mechanical damping constant (B=0) in Fig. 2.7-3. Calculate estimates of the resulting overshoot and settling time for a step current input, beginning at an initial current of 0.
iii) Now consider a closed-loop speed control system as shown in Fig. 2.7-5. Assume that the current regulator dynamics are very fast compared to the outer speed loop and the current regulator gain is high enough so that it is effectively "ideal". Calculate the eigenvalue of this closed-loop system for Kp=100, τz=∞. (Assume B=D=0 again.) Calculate the resulting output speed overshoot and approximate settling time of the closed-loop system for a step speed command input.
Explain the OR Gates - microprocessor? The OR GATE has high or logic 1 output if any of the inputs are high. The output Q is true if input A OR input B is true (or both of t
General Purpose Diodes The general purpose diodes have relatively high reverse recovery time. The diodes are general made by diffusion. They are used in low speed app
Explain the Voltage Regulation? The percent of voltage regulation of a generator is defined as the ratio of the change in voltage from no-load to full-load to the full-load vol

1. Write a MATLAB program to generate and plot the signal x1(n) = [3 2 -2 0 7], n = 0,1,2,3,4.
What is the signal classification of 8085 All the signals of 8085 can be classified into 6 groups Address bus Data bus Control and status signals Power supply and f
The comparison can be made out of two feature 1) Performance and 2) Integrity of Data Write through is better in integrity as it will flush for every writes. Write b
Currents induced in armature conductors of a d.c. generator are alternating. To make their flow unidirectional in the external circuit, we need a commutator. Moreover, these curren
Q. When the quantum step size δv and the step size of f (t) are the same as in , the quantizer is said to have a gain of unity. If, on the other hand, the quantizer has a gain of K
