Design of robust decentralised controllers for MIMO plants with delays through network structure exploitation

A methodology is proposed for the design of robust controllers for retarded and neutral-type time-delay systems, focusing on decentralised and overlapping fixed-order controllers for Multiple Input Multiple Output (MIMO) systems. The methodology is grounded in a direct optimisation approach and relies on the minimisation of spectral abscissa and H∞ cost functions, as a function of the controller or design parameters. First, an approach...
