Chapter 9 PID Controller Tuning ※ Control performance by three goals 1.Controlled-variable performance ― Minimize the IAE of controlled variable 2.Model error―Robustness 3.Manipulated-variable behavior―Excessive variation
3
* Typical feedback control loop
4
Where the combination
5
* Base value of process
6
* IAE vs. controller gain (P)
7
* IAE vs. PI control
8
* IAE vs. PID control
9
* Tuning correlations ◎ Time fraction e.g.
10
* Ciancone correlations (pp.280) (1)PID tuning constants (2)PI tuning constants
11
(1) PID tuning constants
12
(2) PI tuning constants
