Abstract :
A first-principles based nonlinear algebraic model of a rapid thermal processing chamber is used to consider an actuator-sensor selection problem based on static (steady-state) performance. A two step systematic procedure is proposed and illustrated on an example. Actuator groupings are ranked according to the achievable best nominal uniformity level. Once the actuator groupings are determined, the sensor locations are rated according to the best worst-case achievable closed-loop performance
