please solve this problem with detail description. A simple but practical feedback control system is shown below. It is a positioning system or position servo for a large video satellite antenna modeled as a mass having a large moment of inertia, J. An output potentiometer measures the output shaft position, converting the position to a proportional voltage according to vo-Kye. where, e is the output shaft angle in radians and vo is the output potentiometer voltage; Kp is the constant...
control system System Description: The figure 1 and 2 below show, respectively, components and block diagram of a motor and the measurements of velocity (via the tacho unit) and position (via the potentiometer). n represents the gearbox ratio between the rotating shaft and the output shaft. The left-hand side of the diagram represents the controller. A reference set point for the rotating shaft is entered in degrees and this is equivalent voltage. The error is calculated by subtracting the measured...
4. Consider the block diagram shown below where D(s) is a step disturbance input. D(s) Controller Plant R(s) + E(s) C(s) G2(s) Ideally you want your controller design to reject a step disturbance input at D(s). This means that in the steady state for D(s)-1, the value of Y(s) is unchanged (a) Ignoring the input R(s), what is the transfer function器in terms of Gi(s) and G2(s)?

The de motor is a very common and very important piece of hardware in many control systems. The dc servo is essentially a dc motor. When used in an "armature controlled" mode, the dc motor has the following transfer function (refer to p224 and p139, Ogata): 0,(s) V (8) K S(T s +1) where is the output position and Vis the voltage to the motor system. Time Response and Tacho Feedback Compensation Figure 1 shows the dc motor connected as...

2. A feedback control system is subject to disturbances at the actuator input, as shown in the following block diagram. Remember that you need to use the final value theorem (and not the table) when dealing with any other input other than the reference. See the last 3 pages, 12-15, of my steady-state error lecture notes for examples on how to deal with disturbance rather than reference inputs D(s) 1 Y(s) $3+2s2+2s If the reference command is r(t) 1S 0,...
