Control of unstable delayed multivariable processes

This paper proposes a control method for multiple-input–multiple-output (MIMO) unstable systems with multiple time delays, based on Diophantine equation. Genetic algorithm is used to adjust controller parameters. The Smith Predictor is internally unstable when applied to unstable plants. In this approach unstable processes can be handled. Effectiveness of the proposed scheme is illustrated through computer simulation.
