Simulation of Adaptive Control by Instrumental-Variable Identification.

Abstract

This paper presents the use of computer simulation to test the application of the instrumental-variable method of process identification to the adaptive temperature control of a chemical reactor. The method is shown to be stable when used in a closed-loop configuration to update the parameters of a discrete linear model of the reactor. The updated parameters are used to adjust the parameters of a feedback control algorithm. Dynamic information is generated by aperiodic changes in control set-point. Unmeasured disturbances are shown to deteriorate the parameter estimates, but without catastrophic effects. (Author)
