Quadratic Optimal Regulator Design of a Pneumatic Control Valve

Table 2

Settling time, overshoot, and maximum control input of the response to initial condition of the valve.

Method for regulator design	Settling time (sec)	Overshoot (%)	Maximum control input
Pole placement	0.5	0.4	0.9
Full-order observer	0.5	0.15	0.4
Minimum-order observer	0.5	0.25	0.6
Optimal regulator	0.1	0.018	0.005
