- Present a different approach to solve μ synthesis problem in order to obtain more practical controllers.
- Use a simple evolutionary algorithm to solve μ synthesis problem as an optimization problem.
- Use a benchmark system to show effectiveness of the proposed approach to solve μ synthesis problem.
- Compare the proposed controller with Hâ and μ synthesis controllers designed in Robust Control Toolbox of Matlab Software.
In this paper an evolutionary algorithm is employed to address the controller design problem based on μ analysis. Conventional solutions to μ synthesis problem such as D-K iteration method often lead to high order, impractical controllers. In the proposed approach, a constrained optimization problem based on μ analysis is defined and then an evolutionary approach is employed to solve the optimization problem. The goal is to achieve a more practical controller with lower order. A benchmark system named two-tank system is considered to evaluate performance of the proposed approach. Simulation results show that the proposed controller performs more effective than high order Hâ controller and has close responses to the high order D-K iteration controller as the common solution to μ synthesis problem.
