57. A robot arm called ISAC Intelligent Soft Arm Control) can be used as part of a system to feed people with disabilities (see Figure P6.14(a)). The control system guides the spoon to the food and then to a position near the person's mouth. The arm uses a special pneumatically controlled actuator called a rubbertuator. Rubbertuators consist of rub ber tubes covered with fiber cord. The actuator contracts in length when pneumatic pressure is increased and expands in length when...

5. GH(s) is a minimum-phase system which has the Bode plot shown below. It is desired to increase the phase margin by 40 degrees and also increase the closed-loop system bandwidth. Design a lead compensator for this purpose. Determine (1) the ratio of the pole to the zero, α , (2) the frequency where the maximum phase shift from the compensator should be placed, and then (3) the pole and zero. You need not draw the Bode...
