Manual Control: Design a dc motor circuit to drive an assembly line consisting of a conveyor belt moving horizontally. The load on the belt varies depending on the number of goods being moved. The load torque seen by the motor varies from a maximum of 20 Nm to a minimum of 5 Nm. At all loading conditions, the speed of the motor must be maintained constant and equal to 150 rpm. a. To achieve the required operation, the armature voltage of the motor is adjusted by a single-phase, full-wave, ac/dc converter. The input voltage and frequency to the converter are 240 V (rms) and 50 Hz. (Hint: Motor type, Motor rating, α range, Supply voltage, and frequency...etc) Automatic Control: Modify the design to automatically adjust the voltage to maintain the speed equal to 200 rpm within the specified torque range. (Hint: control variable, controller type, connection, controller weights..etc)
As part of your role as a maintenance technician working for a medium sized manufacturing company you are employed working on automated control systems and production plant. Your supervisor has stated that there is an investment plan in place and some machinery is due for an upgrade or replacement over the next few years and they have asked you to produce a report relevant to speed control and drives associated with machinery and manufacturing processes. Task 1 A. You are to produce a report relating to ac drives and their use within industry and within this report you are to illustrate the various operating modes of the drives and support this with corresponding circuit (brief), block and waveform diagrams to illustrate the operation of an induction motor on open loop control and how a closed loop control can be used to improve the speed control. In your report you are to give examples of 3 phase voltage and frequency relationships relative to speed control of the machine and briefly…

6. The block diagram of a video tape drive is shown in Figure Q.6. It is important for the quality of the video image that the tape spool is rotated at a particular reference speed, m,. The actual speed of the tape, o, is sensed, and fed back, any error, E(s) being passed to the controller, G(s), which controls the torque motor. The tape is also subject to torque disturbance, D(s) due to frictional and other effects. a) It is proposed to use a simple proportional controller. Assuming no change in reference speed, calculate the necessary proportional gain, K„, if the maximum allowable steady state error is 0.01rad/s in response to a step disturbance torque of 1Nm. b) Derivative action is added to the controller. Calculate the necessary proportional and derivative gains K, and K,, if the maximum allowable overshoot in speed is 20%, and the speed must settle to its final value in less than 0.25s in response to a unit step change in reference speed, assuming no disturbance. c) Using the…
