Summary: | To be cost-effective, most commercial off-the-shelf industrial controllers have low system order and a predefined internal structure. When operating in an industrial environment, the system output is often specified by a reference model, and the control system must closely match the model’s response. In this context, a valid controller design solution must satisfy the application specifications, fit the controller’s configuration and meet a model matching criterion. This paper proposes a method of solving the design problem using bilinear matrix inequality formulation, and the use of Differential Evolution (DE) algorithms to solve the resulting optimization problem. The performance of the proposed method is demonstrated by comparing a set of ten DE variants. Extensive statistical analysis shows that the variants best/l/(bin, exp) and rand-to-best/l/(bin, exp) are effective in terms of mean best objective function value, average number of function evaluations, and objective function value progression. |
