An Iteration Method to Sub-optimal Output Feedback Computer Control of Decentralized Singularly-perturbed Systems

An iteration method is proposed for sub-optimal output feedback computer control of decentralized singularly-perturbed systems. Computer control, decentralized output feedback control, and order- reduced control are three primary goals for this control scheme. The analog to digital transformation technique is used to convert continuous-time state models to discrete-time domain for the controllers which can be implemented by computer and be able to deal with today´s complicated large scale system. Singular perturbation methods are applied to reduce the order of the system. After order reduction, it will help us to analysis the system; reduce the manufacturing process and cost. The contribution of this research provides a sub-optimal computer control algorithm for large-scale and high-dimension systems with strong potential for practical applications, such as power distribution and communication networks.
