Write a computer program that implements the estimation of a first-orderplus-dead-time transfer function with the tangent method and then determine the PID parameters using the Ziegler-Nichols formula. Apply the program to the system
and simulate the response of the control system when a set-point step change and a load disturbance step are applied. Discuss the choice of the time constant value based on the results.
Discuss the consequent effects on the real and reactive power losses, and on the voltage drop across the series impedance of the transmission system.
A small portable generator can be started by pulling on a cord to start the engine and supplies ac current directly to an installation. What can you conclude about this generator in terms of its excitation?
Develop an understanding of overall concepts of various management functions - Demonstrate knowledge of acquisition of information
The area of each plate in a differential capacitor sensor is equal to 4 cm2. Calculate the equilibrium capacitance in air for each capacitor assuming that the equilibrium displacement for each capacitor is equal to 2 mm.
Explain Non-adiabatic operations of flow reactors. 15In non-adiabatic operations, heat interchange with the surroundings will beaccounted. The conversion can be defined as the ratio of the net heat still needed after heattransfer to raise the feed..
Find the minimum utility requirements for this process, for a minimum approach temperature of 10 °C.
If the operating coil has 1800 turns carrying a current of 1 A, and the gaps are set at 0.125 cm each, find the pull that must be exerted by the spring. You may neglect leakage and fringing.
Write a MATLAB function that uses the transfer function approach to determine the closed-loop system transfer function for a given plant transfer function G(z), desired closed-loop system poles, and observer poles.
Let p be the price of output, and let the factor prices be fixed. If p = 2 how much will the firm produce? If p = 1 how much will the firm produce? What is the profit function of this firm?
The Soave-Redlich-Kwong equation is a commonly used cubic equation of state, second in popularity only to the Peng-Robinson Equation of state. In this problem, just derive the two equations (7.66) given in the problem.
A larger distillation tower is needed for the same mixture, and it has been decided to use a 12-in. inside-diameter tower with the same type and size of packing.
Solid NH4NO3 (ammonium nitrate) decomposes on heating to 400°C, forming N2O gas and water vapor, H2O. (a)Write a balanced chemical equation
