Consider a salient-role generator delivering power through a short transmission line to an infinite bus V∞=1∠0°, |Ea|=1.5. The active power delivered to the infinite bus is 0.7. We are given the generator reactances Xd=1.6 and Xq=1.0 and the line reactance XL=0.3. Neglect resistances, draw the phasor diagram and find Ea and Ia.

On logisim or any circuit building program, design a counter that counts 9,8,7,6,5,4,3,2,1,0 then back to 9. After, add to it's output a 7 segment decoder and it's display.

thank you!

electronics example. Add the references used for your answer.

could someone describe briefly the two main methods of tuning a PID controlled system and say which one would not be suitable for tuning a critical system such as a power plant. The answer should not be too long (maximum 500 words) and preferably not hand written. Thanks

another method of multiplexing involves the use of tri-state devices.   First of all, how are multiplexers used and second, what are tri-state devices and why do we really care about tri-state device (yes we most emphatically DO CARE.. they are very important).

Sketch a block diagram of the following system. The input should be the desired position in mm, the output should be the actual position in mm. Show the plant to be controlled, G(s), as well as the sensor, H(s), and controller, C(s). All inputs and outputs should be labeled with signal names and units.

Problem Statement:

The 3D print head mass is 2.2 kg.

The structure that raise and lowers the head has a mass of 0.8 kg (including its motor).

The cross arm has a mass of 4 kg.

The design uses an air bearing slide on the cross arm. You may assume the slide is frictionless.

The carriage position is measured by a linear encoder that can be modeled as a continuous sensor.

The team has selected an actuator with a constant ratio between force and voltage: 200N/V

A unity gain amplifier drives the motor and can generate voltages between -24V and 24V

The print head has a range of motion of 0 mm on the left side to 600 mm on the right side.
