Abstract :
In this paper we introduce an adaptive structure that dynamically calculates the gains of a PI controller, in presence of parametric disturbances in the controlled process approach, with the purpose of maintaining a desired pole assignment in closed loop, besides fulfilling a specified time closed loop performance. The designing procedure presented in this work is useful when the process to be controlled can be satisfactorily accomplished with a first or second order transfer function.
