MULTIVARIABLE CONTINUOUS-TIME GENERALIZED PREDICTIVE CONTROL - A STATE-SPACE APPROACH TO LINEAR AND NONLINEAR-SYSTEMS

The multivariable continuous-time generalised predictive controller (C GPC) is recast in a state-space form and shown to include generalised minimum variance (GMV) and a new algorithm, predictive GMV (PGMV) as s pecial cases. Comparisons are drawn with the exact linearisation metho ds of nonlinear control, and it is noted that, unlike the transfer fun ction approach, the state-space approach extends readily to the nonlin ear case. The resulting state space design algorithms are conceptually and algorithmically simpler than the corresponding transfer function based versions and have been realised as a freely available Matlab too l-box.
