Question
This figure shows the duty cycle which needs to be adjusted by your controller. The objective is to keep the speed of the shaft at 1200 rpm while the load torque is changing. You need to disconnect the duty cycle control input block and replace it with your closed loop feedback controller.
The simulation runs for 30 seconds. You need:
Design a controller to keep the motor speed constant at 1200 rpm for entire 30 seconds. There should not be overshoot or undershoot of speed more than 10 rpm and settling time should be less than 5 seconds. The loads are applied in intervals of 5 seconds.
Discuss why you selected the controller you have and what benefits it brings.
Show that the voltage is adjusted properly according to the load.
Measure the electric power delivery to the motor for entire 30 seconds.
Project Description. Speed of DC motors is controlled by the applied voltage at their terminal. The DC-DC boost converters are mostly used to adjust the vo at their terminals. The voltage of boost converters is adjusted by adjusting the PWM duty cycle of the switching transistor.

Measure the electric power delivery to the motor for entire 30 seconds 5. Write a professional report and document your work, insert clear high quality figures that shows you have achieved the control performance requiredExplanation / Answer
Taco no longer makes this product and we don't have any replacement elements. The PANELTROL was designed to reduce the water temperature being supplied to a radiant panel loop. The reduction in water temperature allowed the radiant loop to operate at a lower temperature than the boiler, which might be needed for other higher temperature requirements. The return water from the radiant loop is used to temper the hot water. Taco does make a new tempering valve, the 5000 Series Valve, that could take its place. The PANELTROL had 1¼" connections but our 5004-C1 should work.
