Abstract

A nonlinear adaptive control strategy is derived from the biological control system that regulates arterial blood pressure. The parallel control system consists of a linear controller and a nonlinear controller that interact via a reciprocal lateral inhibitory mechanism. The linear controller design is based on an empirical linear model, while the nonlinear controller is constructed from locally supported radial basis functions that are updated on-line using a model reference adaptive control technique. The control strategy is evaluated using a simple model of a pH neutralization system
