A unity feedback control systems for a robot submarine has a plant with a third-order transfer function
G(s) = K / (s(s + 10)(s +50))
We want the overshoot to be approximately 7.5% for a step input and the settling time (with a 2% criterion) of the system be 400ms. Find a suitable phase-lead compensator by using root locus methods. Let the zero of the compensator be located at s = -15, and determine the compensator pole. Determine resulting Kv.
Each pole of a 100kW, 250v flet-compound generator has a shunt field of 2000 turns and a series field of 7 turns. If the total shunt field resistance is 100 ohms, calculate mmf when the machine operates at rated voltage.
The following measurement were made on a two-port resistive circuit. With port 1 open, V2 =15V, V1 = 10 V, and I2 = 30 A. With port 1 short-circuited, V2 = 10 V, I2 =4 A, and I1 = -5 A. Find the parameters of the z-parameter two-port.
The signal m(t)=6sin(2*pi*t) volts is transmitted using 4-bit binary PCM system. The quantizer is of the midriser type, with a step size of 1v
An electric field of 3.10×105 is desired between two parallel plates, each of area 36.0 and separated by 0.620 of air.What charge must be on each plate?
Three towns A, B & C are situated at the corners of an equivalent triangle of side 30 km. It is proposed to supply power to extent of 30 MW, 10 MW, 20 MW to A, B & C respectively from one substation. Where should substation be located to minimize ..
Determine log10 0.2 = log10 18/90, and compare to log10 18 - log10 90.
Supply the quantisation levels (including zero) that are available. Do this for both the three and 4-bit ADC in table form. What is the resolution of each quantizer?
1. Express the Boolean function f(X,Y,Z) = XY + X(Y + Z) in sum of products form showing the sum all nonzero minterms. 2. Express the Boolean function f(A,B,C,D) = A(B + BC) + ACD in sum of products form showing the sum all nonzero minterms.
Apple A5 die size is 122mm^2 when fabricated in 45nm technology. Assume they purchase 300mm wafers at a foundry for $ 2.5K /wafer. Assume a yield of 70%. What is Apple's approximate die cost?
What fixed point unsigned representation, with how many bits and how many bits to the left of the binary point, should we use if we need to represent numbers in the range 0 - 100 with a resolution of .001 or better
Important information about Examination of a digital radio link A. A digital radio link operates at a frequency of 75 MHz and uses ideal RRC filters with nroll off factor r = 0.2 in the transmitter
Design I/O wiring to control forward and reverse 12Vdc motor using PLC OMRON CJ1M. Consider that the forward movement of the motor will be controlled by a forward button and the reverse movement of the motor will be controlled by a reverse button
