The satallite system below is controlled using reaction wheels. The torque wheel input for the system is u(s) and the satallite attitude is Ө(s) For a strong communication link Ө needs to be a value where the satallite atenna is pointing at the ground station The transfer function for this system will be shown in the picture. Design a feedback control system that sets the closed loop damping ratio at 0.8 and the natural frequency is at 10 rad/sec.
Consider the level loop shown in Fig. 5-3.2. The steady-state operating conditions are f i = f o = 150 gpm and h = 6 ft. For this steady-state the FC valve requires a 50 % signal. The level transmitter has a range of 0 to 20 ft. A proportional only controller, with Kc = 1, is used in this process. Calculate the offset if the inlet flow increases to 170 gpm and the valve requires a signal of 57 % to deliver this flow. Report the offset in % of scale and in feet.
1. Give an example of open loop and closed loop system (one example each). Also state the input, control system, feedback and output parameter. Example. 1. Open Loop - Water Heater: Input - Water Temperature (Cold) System - Heating Element Output - Water Temperature (Hot) 2. Closed Loop - Air-conditioning System Input - Desired Room Temperature Control - Motor controller/Compressor/ACU Feedback - Temperature Sensing Output - Room Temperature
One of the disadvantage of negative feedback loop is lag caused because it can only be exerted after controlled variable has been disturbed. In order to minimize lag between a change in a controlled variable and the action of the effector, it is advantageous for the body to anticipate any likely change. Which one of the following physiological mechanism achieves this? Select one: a. Feedbackward control b. Feedforward control c.Positive feedback control d. All of the above e. None of the above
