Abstract :
The paper describes the application of single-input/single-output discrete linear-control theory to control the evaporation of various dielectric material in a vacuum chamber. The process is modelled using a recursive least-squares method and a controller is designed from the model. Process nonlinearity is shown to inhibit the performance of linear feedback control. A compensation is introduced to overcome this difficulty, and an effective final control design is achieved.
