Abstract:

In this paper, robust pole assignment problem for piecewise linear control systems using an improved global harmony search (IGHS) algorithm has been addressed,
which restricts the degrees of freedom in the choice of eigenvectors and has a good convergence. The closed-loop system has a maximum allowable perturbation or uncertainty with
the optimal controller. In contrast to most existing methods, not only the gradient and differentiability information of the nonlinear robust measure objective function is
unconsidered, but also the character of concave or convex about the optimization problem is unconsidered. Finally, the simulation results demonstrate the effectiveness of the
proposed method.
