1) Describe how you would implement it using an open-loop system2) Describe how you would implement it using a closed-loop system
3) What are the type(s) of sensors required in each case?4) Compare and contrast the potential problems that may arise in implementing the control system as an open-loop vs. a closed-loopsystem.5) Assume that one of the pumps uses a ¼ hp DC shunt motor with an input voltage of 115 VDC that pulls 1.6 A running at 1,500 rpm. The field resistance for the motor is 600 O and the armature resistance is 8.5 O. Find the constants Kemf and KT for this motor.The process to be controlled described earlier is a relatively simple process that can be implemented using straightforward methods. However, more complex processes require different types of control approaches.6) Describe Ratio Control and give an example of a situation in which you would use it.7) Describe Adaptive Control and give an example of a situation in which you would use it.8) Describe the similarities and differences between Cascade Control and Feedforward Control In most situations it is also desirable to send information from the process to be controlled, -in this case the 500 gallon tank- to a central station for processing and storage. This information can be transmitted and processed in different ways.9) Fieldbus is one of the methods used to transmit large amounts of process information. Describe the advantages and disadvantages ofusing Fieldbus.10) In the case of a problem in the communication process in general (not just using Fieldbus), describe how you would troubleshoot acommunications problem at the physical layer. Describe also the tools that you would use to troubleshoot the communications problem at thedata link layer.
Determine which of the machines with the following specifications is realizable with a finite number of states. 1) A machine is to produce an output of 1 whenever the number of 1's in the input sequence exceeds the number of 0's.
What device can be used to connect to data bus with enable/disable capability. When all these kind of devices tied to the bus are disabled, what logic level is on the bus line.
A DTMF signal with duration T seconds can be modeled as a sum of two cosine signals with frequencies frand fc, multiplied by a rectangle function. For example, the DTMF signal for "1" is g1(t) = rect (t/T) * [cos(2pi*687t)+cos(2pi*1209t)]
In a balanced three-phase system the Y-connected impedances are 3∠60°Ω. If V_bc=480∠-75° V, find current of phase "b" in polar form.
1.) (a) What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers. (b) What is the advantage of using the 2's-complement system to represent signed numbers.
1) Determine the resistance range for resistors with the following color codes: a. Red-Orange-Orange-Silver b. Gray-Red-Red-Gold c. Yellow-Purple-Yellow-Gold 2) Determine the color code for the f..
Rectifying a sinusoidal provides a way to create a dc source. In this problem we consider the Fourier series of the full wave and half wave rectified signals. The half wave rectified signal xf(t) has a period T0 = 1 and its period from 0 to 1is: x..
find the force between a charged circular loop of radius b and uniform charge density l and a point charge Q located on the loop axis at a distance h from the plane of the loop. what is the force when h>>b, and when h=0 plot the force as a functio..
A ones count circuit has 3 inputs A,B,C and 2-bit output YZ. YZ is 00 if none of the inputs are 1; YZ is 01 if 1 of the inputs is 1; YZ is 10 if 2 of the inputs are 1; YZ is 11 if 3 of the inputs are 1. Design a 6-input circuit that outputs a true
Draw a strain gauge circuit and its external components to attach to a conveyor mounted only at the ends to measure the load at the center of the conveyor. What type of testing would you need to do to establish a baseline and calibration curve for..
Measurments taken of a square-wave signal using a frequency-selective voltmeter(called a spectrum analyzer) show its spectrum to contain adjacent components(spectral lines) at 98KHz and 126 KHz of amplitudes 63 mV and 49 mV
Implement a high-speed multiplier which will multiply two 2-bit binary numbers (B1B0 and C1C0) using a 16X4 PROM (lookup table implementation). List the content of all the memory locations in the PROM and describe the operation.
