The classical multivariable Smith predictor is extended to multivariable nonsquare systems with multiple time delays where the number of process inputs is higher than the process outputs. Pairing for input and output variables is carried out using the block relative gain technique. Simplified decoupling method is applied to design the decouplers. The decoupled processes are modeled as first-ord...

On the Noninteracting Control of Nonlinear Multivariable Systems Hidekatsu TOKUMARU and Zenta IWAI (Faculty of Engineering, Kyoto University, Kyoto) (Received January 10, 1968) In this paper, the noninteracting control of nonlinear multivariable systems is studied. In the first place, it is showed that the noninteracting control problem is avariational one. Necessary conditions and sufficient c...

In this paper an approach is presented to estimate a linear multivariable model on the basis of (noisy) frequency domain data via a curve tting procedure. The multivariable model is parametrized in either a left or a right polynomial matrix fraction description and the parameters are computed by using a two-norm minimization of a multivariable output error. Additionally, input-output or element...

This paper proposes an auxiliary model based hierarchical least squares algorithm for multivariable Box-Jenkins-like systems using the hierarchical identification principle. To improve the computational efficiency, a multivariable system is decomposed into two subsystems by using the data filtering technique. Furthermore, this paper presents a data filtering based auxiliary model hierarchical l...

A novel multivariable laboratory process that consists of four interconnected water tanks is presented. The linearized dynamics of the system have a multivariable zero that is possible to move along the real axis by changing a valve. The zero can be placed in both the lefr and the right half-plane. I n this way the quadrupletank process is ideal for illustrating many concepts in multivariable c...

The emergence of wireless sensor network as has raised the need for cheap wireless indoor localization technique This paper considers the problem of fingerprinting indoor localization based on signal strength measurements RSS. A new approach based on Fuzzy logic has been put forward. The proposal makes use of k-nearest neighbor classification in signal space. The localization of target node is ...

Fractional order calculus is currently experiencing a wide application in controlling different types of processes. The focus has been directed towards the design of robust controllers for single-inputsingle-output systems, with very few tuning examples for the multivariable ones. The purpose of the present paper is to describe a simple and effective method for designing a multivariable fractio...

The proximate analysis is the most common form of coal evaluation and it reveals the quality of a coal sample. It examines four factors including the moisture, ash, volatile matter (VM), and fixed carbon (FC) within the coal sample. Every factor is determined through a distinct experimental procedure under ASTM specified conditions. These determinations are time consuming and require a signific...
