In this paper, conventional lead-lag power system stabilizer (CPSS) is designed to damp electromechanical oscillations. CPSS parameters settings are computed using linear control theory. A new technique based on particle swarm optimization PSO is proposed to optimize the parameters settings of CPSS. The problem is formulated as an optimization problem, the objective is to compute the optimal parameters...
The symmetric control systems have some interesting properties. This paper studies a class of symmetric system consists of a collocated second-order plant and a static output feedback controller. For the system, it is known that the internal stability and the robustness of the closed-loop system are guaranteed based only on the non-parametric structure condition. Our objective is to propose an optimal...
This paper addresses the problem of normalized anisotropic optimal controller order reduction by means of anisotropic balanced truncation. This controller is the solution to the problem of normalized anisotropy-based stochastic Hinfin optimization. An example of application to flight control in a windshear is given.
This work presents a methodology for the design of a model-based networked control system for spatially distributed processes described by linear parabolic partial differential equations (PDEs) with measurement sensors that transmit their data to the controller/actuators over a bandwidth-limited communication network. The central design objective is to minimize the transfer of information from the...
A novel integration of design and controllability method is proposed for the process design under uncertainty. The key idea is to integrate the robust eigenvalue assignment with the robust optimal design to achieve the desirable design performance and dynamic performance. The robust optimal design is to have a trade-off between robustness and optimization for the steady-state economic design, and...
Optimal locations and design of robust multimachine power system stabilizers (PSSs) using heuristic algorithms is presented in this paper. The tuning of PSS via a non-dominated sorting genetic algorithm (NSGA-II) is performed to obtain a set of compromise speed-damping solutions. The stabilizers are tuned to simultaneously shift the lightly damped and undamped electromechanical modes of all plants...
An optimal procedure for designing co-ordinated controllers of power system stabiliser and flexible ac transmission system devices is developed for achieving and enhancing small-disturbance stability in multi-machine power systems. A constrained optimisation approach is applied for minimising an objective function formed from selected eigenvalues of the power systems state matrix. The eigenvalue-eigenvector...
