Description |
omega – imaginary component of the pole |
Imaginary component w of the poles of the closed control loop. The dynamic behaviour of the closed-loop is defined by its poles:
|
alfa – real component of the pole |
Real component a of the poles of the closed control loop. The dynamic behaviour of the closed-loop is defined by its poles:
|
Control law:
|
where ek is control error ( ) and controller parameters , , and are calculated by solving following diophantine equation:
|
where polynomials are as follows:
|
|
|
|
|
Solving the diophantine equation leads to following relations for controller parameters:
