uestion 1 1. Consider the analogue feedback position control system shown below in Figure 1, where the 2 variable resistors, labelled Selected Position and Position Output, represent the input and feedback sensors, respectively. Draw the equivalent digital feedback control system, clearly showing all the blocks involved (including the controller, actuator, plant sensor, and amy additional blocks.) and the relevant signals involved as well. Assume here that a computer is to be used for entering the selected (i.e. desired) position and receiving the feedback ing Figure 1 2. Consider the feedback control system shown below in Figure 2, where x is the input, yis the output, d is the disturbance, and KC,K, K,, K are the gains of the controller, actuator, plant and sensor, respectively. Case 1: open-loop control Remove K s from Figure 2) a) Find the expression, in terms of the gains K and/or K p of BOTH the input-output OL gain, G and the disturbance-output gain d 0 b Can we reduce the effect of the disturbance d on the ouput y without affecting the input output gain G OL. Assume here that the plant gain can be varied. Justify your answer. uestion 1 1.
