Controller design with regional pole constraints
TL;DR: In this paper, a design procedure was developed that combines linear-quadratic optimal control with regional pole placement, in which the poles of the closed-loop system are constrained to lie in specified regions of the complex plane.

Effective chaotic orbit tracker: a prediction-based digital redesign approach
TL;DR: In this paper, the authors developed an effective digital tracker for continuous-time chaotic orbit tracking, which is insensitive to numerical errors and allows for a relatively large sampling time, which can be important in some applications such as in chaotic biological systems.

Load Disturbance Resistance Speed Controller Design for PMSM
TL;DR: This paper presents an linear-quadratic-regulator-based proportional-integral-differential equivalent controller design method for a permanent-magnet synchronous motor based on a multi-objective observer in which observation error is purposely retained and utilized in load disturbance compensation.

Algebraic approach for selecting the weighting matrices of linear quadratic regulator
TL;DR: In this article, an algebraic approach for selecting the weighting matrices of linear quadratic regulator (LQR) for trajectory tracking application is proposed, which directly translates the system requirement into cost function, so that an optimal performance can be obtained via a systematic approach.

Paper: The time-invariant linear-quadratic optimal control problem
TL;DR: This paper provides a review of one of the basic problems of systems theory-the general time-invariant optimal control problem involving linear systems and quadratic costs, developed using simple properties of dynamical systems and involves a minimum of 'hard' analysis or algebra.

Design of optimal control systems with prescribed eigenvalues
TL;DR: In this paper, a quadratic performance index together with a set of prescribed closed-loop eigenvalues are considered as criteria for designing linear multi-variable control systems and a method is developed for finding the weighting matrix elements that correspond to the given eigen values.

Brief paper: Determining quadratic weighting matrices to locate poles in a specified region
TL;DR: A new procedure of selecting weighting matrices in linear quadratic optimal control problems (LQ-problems) is proposed, which has merits of an LQ-problem as well as a pole-assignment problem and will be useful for designing a linear feedback system.

Optimal pole shifting for continuous multivariable linear systems
TL;DR: In this paper, a method for shifting the real parts of the open-loop poles to any desired positions while preserving the imaginary parts is presented, based on the mirror-image property which has been reported by Molinari.
