Abstract: We present in this paper a new metaheuristic using Ant System metaheuristic to search an optimal command law in LQR sense that gives for a feedback system a given values by pole assignment. In fact, these hybrid techniques of conventional and non conventional methods present a good compromise between the simplicity of use and the quality of proposed solutions in a reasonable computing time. The results obtained by using this technique show its efficiency in the proposed problem and can be considered as a competitive method for those issued from a complicate mathematic formulation.

Keywords: pole assignment; LQR technique; optimisation; constraints; ant systems; metaheuristics; optimal command law; linear quadratic regulation; feedback control.
