Multiobjective Robust Control with HIFOO 2.0
Multiobjective control design is known to be a difficult problem both in
theory and practice. Our approach is to search for locally optimal solutions of
a nonsmooth optimization problem that is built to incorporate minimization
objectives and constraints for multiple plants. We report on the success of
this approach using our public-domain Matlab toolbox HIFOO 2.0, comparing our
results with benchmarks in the literature
Variance-constrained multiobjective control and filtering for nonlinear stochastic systems: A survey
The multiobjective control and filtering problems for nonlinear stochastic systems with variance constraints are surveyed. First, the concepts of nonlinear stochastic systems are recalled along with the introduction of some recent advances. Then, the covariance control theory, which serves as a practical method for multi-objective control design as well as a foundation for linear system theory, is reviewed comprehensively. The multiple design requirements frequently applied in engineering practice for the use of evaluating system performances are introduced, including robustness, reliability, and dissipativity. Several design techniques suitable for the multi-objective variance-constrained control and filtering problems for nonlinear stochastic systems are discussed. In particular, as a special case for the multi-objective design problems, the mixed H 2 / H â control and filtering problems are reviewed in great detail. Subsequently, some latest results on the variance-constrained multi-objective control and filtering problems for the nonlinear stochastic systems are summarized. Finally, conclusions are drawn, and several possible future research directions are pointed out
A Brief Analysis of Gravitational Search Algorithm (GSA) Publication from 2009 to May 2013
Gravitational Search Algorithm was introduced in year 2009. Since its introduction, the academic community shows a
great interest on this algorith. This can be seen by the high number of publications with a short span of time. This paper analyses the publication trend of Gravitational Search Algorithm since its introduction until May 2013. The objective of this paper is to give exposure to reader the publication trend in the area of Gravitational Search Algorithm
