Figure 3a show a block diagram of a model for an attitude-rate control system. The closed-loop transfer function for this system is C(s) R(s) R(s) 2s +0.1 +0.15² +68+0.1 The unit-step response of this system is shown in Figure 3b. The response shows high frequency oscillations at the beginning of the response due to the poles ats=-0.0417+j2.4489. The response is dominated by the pole at s=-0.0167. The settling time is approximately 240 sec. It is desired to speed up the response and also eliminate the oscillatory mode at the beginning of the response. Design a suitable compensator such that the dominant closed-loop poles are at s=-2±/2√3. Hydraulic servo 1 2s +0.1 s² + 0.1s +4 Aircraft Rate gyro C(s)
