Generalized Lqg Approach to Self-Tuning Control. Part 1: Aspects of Design. Part 2: Implementation and Simulation

摘要

An explicit method based on minimization of a multistage cost-function and a Controlled Autoregressive Integrated Moving Average plant model formulated in state-space is presented. The method extends the design features of the Generalized Minimum Variance scheme to the multistage case; these can be used to tailor the closed-loop response of the system. The approach is shown to be robust against wrong a priori assumptions made about the plant dead-time or order, thus maintaining good servo and disturbance rejection properties.
