Singularly perturbation method applied to multivariable PID controller design

Proportional integral derivative (PID) controllers are commonly used in process industries due to their simple structure and high reliability. Efficient tuning is one of the relevant issues of PID controller type. The tuning process always becomes a challenging matter especially for multivariable sy...

This motivates the use of singularly perturbation method into the multivariable PID (MPID) controller designs.
