A synthesis method for multipole control systems

Design of set point regulators for processes involving time delay

“…In order that the responses C,(t) and Cz(t) in Figure 1 match, it is necessary that Equation 1 is generally known as the synthesis equation. Its use in controller design (for 7 = 0) dates back several decades (Freeman, 1957;Cohen and Coon, 1953). An elegant exposition of the technique is available in papers by Sain (1977, 1985), Sain et al (1981), and Sain and Peczkowski (1985).…”

On-Line Control of a Nonlinear Multivariable Process

“…Most of this work is of a theoretical or simulation nature. Several representative examples are the work of Boksenbom and Hood as discussed by Tsien (1954), and the papers of Kavanagh (1957), Freeman (1957Freeman ( , 1958, Mesarovic (1963), Chatterjee (1963), Foster and Stevens (1967), Greenfield and Ward (1967), and Kleinpeter and Weaver (1969). Most linear techniques employ some form of matrix algebra to uncouple the state equations and eliminate the system interactions.…”

Multivariable Systems. Analysis and Feedforward Control Synthesis

“…Since C = M and the determinant of Pcx.v + 0, can be obtained by using Equation 13. [ 2] (5.7, 5.8, 5.9)…”

“…= number of measurements of x which it is planned to make in a kinetic experiment, including the measurement at esses to be controlled are represented by linear, time-invariant models, and it is assumed that the process dynamics are known quantitatively. Some of the techniques discussed have their origin in recent work reported in the electrical engineering literature (2,4). However, several factors make the design of control systems for most electromechanical devices significantly different from that of most process systems.…”
