RECURSIVE DEADBEAT CONTROLLER-DESIGN

A recursive algorithm is presented for the deadbeat predictive control that brings the output response to rest after a few time steps. The m ain idea is to put together the system identification process and the deadbeat control design into a unified step. It starts with reformulat ing the conventional multistep output-prediction equation to explicitl y include the coefficient matrices to weight past input and output tim e histories for computation of feedback control force. The formulation thus derived satisfies simultaneously the system identification and t he deadbeat control requirements. As soon as the coefficient matrices are identified satisfying the output prediction equation, no further w ork is required to design a deadbeat controller The method can be impl emented recursively just as any typical recursive system identificatio n technique.
