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.
Q. A shunt generator gives full load output of 30 kW at a terminal voltage of 200V. The armature and field resistance are 0.05? and 50? resp.. The iron and friction losses are 10
Q. Given that V 0 = 10 V, determine IS in the circuit drawn in Figure.
What makes them sine? Ans) Fourier tells that only a sine wave has no harmonic content. The math works out that if you have any wave shape other than a sign wave, you can brea
how can I simulate air variable capacitors in cst simulator?
Q. What is a differentiator circuit? By introducing electrical reactance into the feedback loops of op-amp amplifier circuits, we can cause the output to respond to changes in
Background Information Electrical machines usually consist of copper windings on steel cores, and their AC resistance is greater than their DC resistance. The power loss has
Q. When input is a triangular wave. When the input fed to differentiating circuit is a triangular wave, the output will be a rectangular wave. During the period OA of

What is macro? A macro is a group of instructions written within brackets and recognized by a name .This is used when a repeated group of instructions is too short or not app
Q. Explain Read-only memory? ROM is nonvolatile (because it maintains its contents even when its power is shut off) and is used to store data and programs that do not change du
