# Improved Particle Swarm Optimization on PID Tuning
|
|
This dir is belong to Control System class contains with Tuning PID with ZN1 and PSO on motor system.
|
|
|
|
## Software
|
|
This program ran in Matlab
|
|
|
|
## Variables
|
|
`s = tf('s');` defines `s` as 'frequency domain' for transfer function and will be used further.
|
|
```
|
|
J = 0.01;
|
|
b = 0.1;
|
|
K = 0.01;
|
|
R = 1;
|
|
L = 0.5;
|
|
```
|
|
Those variable comes from BLDC control system.
|
|
```
|
|
c1=2; c2=2; w_max = 1; w_min = 0.1; particles=50; iterations=100;
|
|
var=3; e_max = 1; e_min=0.1;
|
|
|
|
% Search limit
|
|
lim_min = 0;
|
|
lim_max = 2500;
|
|
```
|
|
Variable above is the constant for PSO tuning.
|
