Commonly, complex and uncertain plants cannot be faced through well-known linear
approaches. Most of the time, complex controllers are needed to attain expected stability …

Tuning the parameters of a controller is very important in system performance. Ziegler and
Nichols tuning method is simple and cannot guarantee to be effective always. This paper …

The work described in his paper aims a exploring he use of Soft Computing techniques for
designing a controller to perform control of level in a spherical tank. First, system …

The design of proportional integral derivative (PID) controller based on internal model
control (IMC) principle with a new form of filter is presented to realize the controller to …

Nonlinear processes abound in the chemical industry. Although linear controllers work for
some of these systems, processes that contain highly nonlinear behavior typically require a …
