c) Cutting forces should be kept constant during machining operations to prevent changes in spindle speeds or work position. Such changes would deteriorate the accuracy of the work’s dimensions. A control system is proposed to control the cutting force. The plant is difficult to model, since the factors that affect cutting force are time varying and not easily predicted. However, assuming the simplified force control model shown in Figure Q2(c). (i) Show the closed-loop transfer function for the system of the system as below K(s+3) T(s)= s* +7s° +14s² + (8+K)s+3K
