QUESTION 1 A numerical path-controlled machine turret lathe is an interesting problem in attaining sufficient accuracy. A simplified design of the turret lathe control system can be modeled with equation below 0.2KR G(s)=G(s)P(s)=G₂₁(s) (0.2s+1)(0.001s² +0.02s) It is necessary to attain an accuracy of 5x10-4 cm, and therefore a steady-state position accuracy of 2.5% is specified for a ramp input. 1. Plot or sketch a root locus. 2. Design a cascade compensator to be inserted before the silicon-controlled rectifiers in order to provide a response to a step command with a percent overshoot not greater than 5%. A suitable damping ratio for this system is = 0.7. The gain of the silicon-controlled rectifiers is KR = 5
