Abstract

The contribution deals with decentralized control of multi input-multi output continuous-time dynamic systems. The model of the controlled plant as well as the control design are formulated in a delta operator form. The decentralization of a MIMO plant is performed in the matrix fraction description. Control synthesis consists of local and global control loops. The local control design is obtained via Diophantine equations in delta polynomials. The global control strategy ensures asymptotic stability of the entire control system. The self-tuning (adaptive) property is based on real-time recursive identification. Proposed strategies are demonstrated by the simulation of control of a non-linear chemical plant.
