The heater is driven from a voltage-controlled power supply, the voltage V1 being derived from a potentiometer. The output temperature, 0 degree, is subject to disturbances, 0D, because of changes in the ambient temperature. It is proposed to apply 'disturbance feedback control, to the system by the inclusion of a transducer that measures the external temperature and feeds a signal back to the input via a proportional controller of gain H.
Determine the required value of H to eliminate the effect of the disturbance.
What is the input to our control system called - What would we expect its final value to be (the value as time approaches infinity) - Determine the equation that linearizes the sensors output between temperatures of 0oC and 100oC.
An aluminum casting that has a mass of 10 kg sits on a steel surface. How much force will be necessary to get it to start sliding. The static coefficient of friction (mu) for aluminum on steel is 0.61.
The simple inexpensive hydro turbo-generator (turbine mated with electric generator) that you intend to buy has a working efficiency of 60%. Answer the following (show your work).
A conducting sphere of radius R is spinning at an angular speed ! in presence of an uniform magnetic field ˆzBo. Find the emf induced between north pole N and any point on the equator E. Hint- what is the emf induced between two end points
A star-bus hybrid topology consists of a main three branch star toplogy with each branch connecting three stations in a bus topology. This toplogy is changed to a new bus-ring hybrid topology with main five station bus topology.
In an electricity experiment, it was observed that as the potential difference in volts across a thin platinum wire increases the current in amperes changes as follows: (V,I)=(0,0), (1.0,0.112), (3.0,0.337), and (6.1,0.675).
Convert the first-order Butterworth low-pass prototype, H(z) = 1 / s+1 to a digital IIR filter using impulse invariant method when sampling frequency is 1 Hz.
the electric field srength E due to an infinite line of chargeis given by E = λ/(2πrεo), where λ is the charge per unit length and r is the radial distance from the wire. a, show that this formular for E still has the units of N/C.
A 100mF capacitor is connected in series with a 10 kW resistor and a 10-VDC source for 2 seconds. Then it isdisconnected quickly and connected to a single resistor of 1kW. (a) Write the capacitor voltage,vc(t), for 0
What is Light Emitting Elements and Their Types ? Please Explain every Element and type .
contrast the electron and hole drift velocities through a 10-µm layer of intrinsic silicon across which a voltage of 5 V is imposed. Let µn = 1350 cm²/V·s and µp = 480 cm²/V·s.
A number consists of multiple characters when written. In the software the numbers are stored as a binary value ultimately at the lowest level of the code translations. The compiler does the translation from binary to hex to decimal.
