Question
7.53 A simplified model for the control of a flexible robotic arm is shown in
Fig. 7.98, where
k/M = 900 rad/sec?,
y = output, the mass position,
u = input, the position of the end of the spring.
Problems 629
M
(a) Write the equations of motion in state-space form.
(b) Design an estimator with roots at s = -100 + 100j.
(c) Could both state-variables of the system be estimated if only a
measurement of j was available?
(d) Design a full-state feedback controller with roots at s = -20 + 20j.
(e) Would it be reasonable to design a control law for the system with
roots at s = -200 + 200j. State your reasons.
() Write equations for the compensator, including a command input for
y. Draw a Bode plot for the closed-loop system and give the gain and
phase margins for the design.
