A new method of applying linear matrix inequalities (LMIs) to multi-objective eigenstructure assignment is put forward. Since there is always a degree of freedom in eigenstructure assignment using state or output feedback, it is available to use this kind of freedom in designing a system to satisfy some additional specializations. With the help of LMI technology, a controller insensitive to pertubation and good in robust stability is realized. And the result of a practical example shows that the method is very useful in flight controller design.
In this paper, a novel nonlinear current-limiting controller that maintains the desired power balance in a hybrid microgrid, is proposed for interlinking converters (ICs). The RMS value of the IC current is analytical...

Nonlinear optimization is the foundation of multiobjective programming. In this paper, our focus is augmented Lagrange multiplier(ALM) method which is employed in constrained nonlinear optimization propositions. A dynamic approach is raised for minimization subproblem in augmented Lagrange multiplier method and a neural network alternative algorithm for general constrained programming is proposed.

The major efforts regarding this analysis, on algorithmic development, and on computations deal with the flow and temperature control and their optimization. This study treats the steady state in order to avoid the unsteady problems. The paper's analyses, i.e. the numerical analyses, and computations have addressed two important types of controls which are the air flow and the temperature. The principal object of this paper is to control several important characteristics of a chemical process by using an automatic device for optimization and system identification;in each case one intends to control the temperature degrees and the air pressure values in the same time, starting from a mechanical apparatus connected at a computer where there are installed the respective control software;this apparatus gives the possibility to set the temperature values at a specified pressure which can produce cold air.
This paper presents a procedure for optimization of the switched reluctance drive, in order to achieve required torque-speed characteristics. SRM configuration and characteristics are given, and experimental verificat...

This paper deals with liquid tanks management faced from an automaticcontrol point of view;the motivation for the study is the need for an automated management strategy for two liquid tanks. The problem that is addressed in this paper is the control of liquid level on each tank by using the PD controller [2]. We encountered with an important problem that is the resulting disturbance from the intersection between these two tanks and the second tank drain, this disturbance has a negative effect in our system. We use in both tanks two valves that are controlled by two DC motors for adjusting the inflow of the liquid for each tank. As far as we know, such performance specifications are unattainable with the old existing methods [1].
