A PI Controller with Adaptive Parameter Tuning

Tuning of PI speed controller

PID controllers are very common in industrial systems applications. The tuning of these controllers is governed by system nonlinearities and continuous parameter variations. In this paper, a complete and rigorous comparison is made between two tuning algorithms. The PI controller was used in a speed control loop in a Direct Torque Control (DTC) scheme applied on an induction motor. The first me...

Tuning methodology for a fuzzy PI controller

A PI-type fuzzy controller with self-tuning scaling factors

In this paper, a self-tuning fuzzy controller with a smart and easy structure is presented. The tuning schemes allow us to tune the scaling factors by only seven rules. The aim of a controller is to obtain a satisfactory performance, such as the rise time, the overshoot, the steady-state error for the step response. Simulation results of a third order system with time-delay show a better perfor...

A Unified IMC based PI/PID Controller Tuning Approach for Time Delay Processes

This paper proposes a new PI/PID controller tuning method within filtered Smith predictor (FSP) configuration in order to deal with various types of time delay processes including stable, unstable and integrating delay dominant and slow dynamic processes. The proposed PI/PID controller is designed based on the IMC principle and is tuned using a new constraint and without requiring any approxima...
