Derivative Effect on Control System

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.
