Consider the control system shown in Figure 8(c), in which a PID controller is used to control the system. The PID controller has the transfer function Gc(s)=Kp(1+1Tis+Tds)G_c(s) = K_p \left(1 + \frac{1}{T_i s} + T_d s\right)Gc(s)=Kp(1+Tis1+Tds) Design the controller.
Consider the mechanical system shown in Figure 4(a). Find the state-space model for this single-input, single-output linear system.
Why linearization is important? Linearize the nonlinear equation: z=x2+8xy+3y2z = x^2 + 8xy + 3y^2z=x2+8xy+3y2 in the region defined by 2≤x≤42 \le x \le 42≤x≤4, 10≤y≤1210 \le y \le 1210≤y≤12.
Draw the schematic diagram for control of a double-acting cylinder.
