A feedback control system with the configuration of Figure has the following parameters: Kp = 0.5 V/rad, Ka = 100 V/V, Km = 2.7 × 10-4 N·m/V, J = 1.5 × 10-5 kg·m2 , and F = 2 × 10-4 kg·m2 /s.
(a) With an applied step-input command, describe the dynamic response of the system, assuming the system to be initially at rest.
(b) Find the position lag error in radians, if the load disturbance of 1.5×10-3 N·m is present on the system when the step command is applied.
(c) In order that the position lag error of part (b) be no greater than 0.025 rad, determine the new amplifier gain.
(d) Evaluate the damping ratio for the gain of part (c) and the corresponding percent maximum overshoot.
(e) With the gain of part (c), in order to have the percent maximum overshoot not to exceed 25%, find the value of the output-rate gain factor.
There are two practical ways of improving commutation i.e. of making current reversal in the short - circuited coil as sparkless as possible. These methods are known as (i) resista
Responses to Exponential Excitations Let us consider Aest as a typical exponential excitation in which A is a constant and s is a complex- frequency variablewith a dimension of
(a) Find the Fourier series for the square wave shown in Figure(a). (b) Let a voltage source having the waveform of part (a) with a peak value of 100 V and a frequency of 10 Hz
Note, the armature current is produced in pulses as the armature rotates under the poles, so the torque also pulsates. This can give rise to extra wear on bearings and the engin
Consider and obtain the values for R S , R 2 , R 1 , and R D . Apply the rule-of-thumb dc design procedure outlined in this section for a JFET with V P = 3V, I DSS = 20 mA, and a
Q. Draw the logic diagram of an SR latch using only NAND gates, and obtain the truth table for that implementation.
