An Innovative Method for Optimization Based, High Order Controller Autotuning

Abstract

A new automatic method to tune the parameters of high order linear controllers is presented. The autotuning is achieved by minimizing, without constraints, a cost function that is related to the open loop shaping problem. The effort demanded from the designer is similar to that required to tune a low order controller, such as proportional integral (PI) or proportional integral differential (PID). The capabilities of the new method are demonstrated on two examples.
