Method of adaptively controlling paint system
First Claim
1. A method of adaptively controlling a paint system for painting vehicle bodies, said method comprising the steps of:
- obtaining an estimated Jacobian that identifies characteristics of the paint system;
using the estimated Jacobian to determine control parameters to be implemented for the next vehicle body to be painted in the paint system;
storing a database of appropriate initial conditions that resulted in satisfactory transient response in a rule-base; and
using the rule-base at start-up of the paint system or if the paint system fails to be satisfactorily controlled.

Abstract
A method is provided of adaptively controlling a paint system for painting vehicle bodies. The method includes the steps of obtaining an estimated Jacobian that identifies characteristics of the paint system and using the estimated Jacobian to determine initial conditions to be implemented for the next vehicle body to be painted in the paint system. The method also includes the steps of storing a database of appropriate initial conditions that resulted in satisfactory transient response in a rule-base and using the rule-base at start-up of the paint system or if the paint system fails to be satisfactorily controlled.
