PID controllers are widely used in many industries and provide acceptable performances with no specific requirement for mathematical knowledge of the plant. However, these controllers, which are tuned for one operating point, are based on the assumption that local linearity holds for the plant to...
This paper presents a simple method for designing a robust controller which can be used on uncertain and non-linear systems. As an extension of the method, the case of delayed systems is examined. The successive steps of the method are: non-linearity analysis and description, system linearization...
