A dc motor position control system has the following transfer system function:H(s) = (55/s)(1/1+0.731s)(1/1+0.0132s).Explain why a PID controller is not a good idea for this process. Use Matlab to design a PD controller for this process. Repeat the design, but this time use a lead-lag compensation network to cancel the 0.731 time constant and replace it with a 0.0731 time constant. Then use MATLAB to design a PD controller for the compensated process. Compared the two designs.
The Signal power to noise power ratio is an important measure of the transmission quality of any channel. If at the receiver there is a 12 dB signal to noise ratio and the received signal power is 50 micro W then calculate the received noise power..
Design a regulated DC power supply. You will have for input a 110 V input source at a frequency of 60 Hz. The Zener diode to use is the 1N4733A (which is available in the lab). The output voltage is to be 5.1 V with a load resistance above 2.2K.
How much power (in watts) is transferred to or from the inductor when the time is 1 ms? The current flowing through the inductor is given by 5e^-200t The inductance is 107 mH
An n-channel MOSFET has a thershold voltage (Vt) of 0.5 V and a width to length ratio (W/L) of 2. If the tansistor generator the curve bleow when the gate to source voltage (VGS) is 1.5V. I D = 0.12mA. VDS = 0.5 V.
(b) Calculate the power dissipated in the MOSFET when the lamp is operating at its rated current. (c) The maximum output current available from the logic system is 30mA. Explain why an NPN transistor would be unsuitable for this appli..
GaAs LED emitting surface size is 180 um by 180 um. The doping levels are NA = 9 E+15 cm-3 and ND = 5 E+17 cm-3. The n-layer is 70 um thick, and the p-layer is 8 um thick.
Compute the energy of the following signals: 1) x(t) = e^-(a|t|) for a > 0 (Notice the absolute value on t) 2) x(t) = (1 - |t|)rect(t/2) (Notice the absolute value on the first t)
An experiment consists of tossing a fair coin four times in succession. What are the possible outcomes Now count up the number of outcomes with three heads. If the outcomes are equally probable, what is the probability of three heads
Single-phase distribution line runs parallel to a ground line and is separated by 2m. During a short circuit, the distribution line experiences a current of 10,000A rms. Determine the magnitude of the separating force acting on a 1m section of the..
how to evaluate power dissipated in the components of an RLC series circuit by using matlab software?
The battery voltage is 20V Resistor3 a resistance of 20ohms. Resistor1 has a resistance of 30. Current flow is 250mA through the circuit. What is the resistance of resistor 3
a) Write the system of linear equations in the form of Ax = b: (b) Use Guass-Jordan method to find A inverse (c) Use A inverse to solve the system of equations. -2x1 + x2 +x3 = -12 4x1 + 2x2 + 4x3 = 7 -x1 + x2 + 2x3 = -3
