“…To name these possibilities, the authors propose a notation in which the indicated number corresponds to the column with the selected element. For instance, in a 3×3 system, configuration 1-2-3 means that elements Kd (1,1), Kd (2,2) and Kd (3,3) are selected; configuration 2-3-1 means that elements Kd (1,2), Kd (2,3) and Kd (3,1) are chosen, and so on. The expression of the controller elements for each configuration is different, which is interesting because some choices can result in non-realizable controller elements.…”

Abstract:This paper presents a new methodology of multivariable centralized control based on the structure of inverted decoupling. The method is presented for general n×n processes, obtaining very simple general expressions for the controller elements with a complexity independent of the system size. The possible configurations and realizability conditions are stated. Then, the specification of performance requirements is carried out from simple open loop transfer functions for three common cases. As a particular case, it is shown that the resulting controller elements have PI structure or filtered derivative action plus a time delay when the process elements are given by first order plus time delay systems. Comparisons with other works demonstrate the effectiveness of this methodology through the use of several simulation examples and an experimental lab process.

“…A gain margin of 10 is chosen as specification in the three loops. The gains k 1 and k 3 are calculated by means of (25). In the second open loop process l 2 (s), the time constant λ of the extra pole is obtained from (28) after specifying ω cp =0.63 rad/min.…”

Abstract-The aim of this paper is to study a new concept of fuel system of a turbojet, to design its control system and to validate its behavior using simulation. AMESim is used to represent the physical system and Simulink has been adopted for the implementation of the control laws. A multi-loop PID strategy is then selected. Simulation tools and different methods of their couplings, including exchange, cosimulation and FMI are benchmarked to find which strategy is the best suitable.

“…In the latter case, more traditional design specifications, such as set-point and load rejection disturbance step response parameters, are considered [11]. In order to provide an effective benchmark, the achievable optimal performance in terms of integrated absolute error for the set-point response has been investigated in [12]. In [13], it is proposed to compare the obtained set-point step response with that achievable by using a PI controller tuned with the internal model control technique.…”

Abstract:Performance assessment and retuning techniques for proportional-integral-derivative (PID) controllers are reviewed in this paper. In particular, we focus on techniques that consider deterministic performance and that use routine operating data (that is, set-point and load disturbance step signals). Simulation and experimental results show that the use of integrals of predefined signals can be effectively employed for the estimation of the process parameters and, therefore, for the comparison of the current controller with a selected benchmark.
