Correlation-Based Tuning of Linear Multivariable Decoupling Controllers

Dominique Bonvin, Ljubisa Miskovic, Alireza Karimi

The recently-proposed method for iterative correlation-based controller tuning is considered in this paper for the tuning of multivariable Linear Time-Invariant (LTI) controllers. The parameters of the controller are updated directly using the data acquire ...

Identification of a Two-Input System: Variance Analysis

Dominique Bonvin, Ljubisa Miskovic, Alireza Karimi

This paper examines the identification of a single-output two-input system. Motivated by an experiment design problem(should one excite the two inputs simultaneously or separately), we examine the effect of the (second) input signal on the variance of the ...

PID Controller Design with Specifications on the Infinity-Norm of Sensitivity Functions

Roland Longchamp, Daniel Garcia, Alireza Karimi

A controller design method using a frequency criterion is proposed in this paper. The frequency criterion is defined as the weighted sum of squared errors between the specified and computed values of the design parameters. These are the infinity-norm of th ...

PID Controller Design for Multivariable Systems Using Gershgorin Bands

Roland Longchamp, Daniel Garcia, Alireza Karimi

A method to design decentralized PID controllers for MIMO systems is presented in this paper. Each loop is designed separately, but the Gershgorin bands are considered to take interactions into account. The method uses different design parameters: The infi ...

Model-Free Precompensator and Feedforward Tuning Based on the Correlation Approach

Roland Longchamp, Alireza Karimi, Mark Edward John Butcher

High performance output tracking can be achieved by precompensator or feedforward controllers based on the inverse of the closed-loop system or the plant model. However, it has been shown that these inverse controllers can affect adversely the tracking per ...
