Ī ball screw type energy regenerative active suspension under fractional order PID control is proposed and studied in order to improve the vibration damping performance of the suspension. Remark 11 (A typical problem of traditional optimization): For systems with two modes, the PI controller tuning derived by the non-convex optimization illustrates the typical handicaps of traditional optimization approaches: 1) They may be applied just to plants characterized by a fixed set of identified parameters considered in the carried out optimization (In the authors noticed a similarity between the controller tunings for the plants with one (fast) and two (fast and slow) modes, but did not notice the tuning similarities for the one-mode static and integral models.). Arduino-Due based thermo-opto-mechanical laboratory system TOM1A also PI control and its generalizations may be expected to yield satisfactory results. Unit disturbance step responses at the input and output of the plant (5) with anti-windup PID m n controller implementation according to Figure 12 (Gc = P ID m n ) followed by saturation to an admissible interval u ∈, Te = 0.9, T dp = 1, Ksp = 1 FIGURE 14. in the majority of situations the plant has a monotonic step response which may well be approximated by the FOTD model, with respect to Remark 10 in Section VI-A.
