A numerical method is developed for the real-time computation of neighbouring optimal feedback controls for constrained optimal control problems. The first part of this paper presents the theory of neighbouring extremals. Besides a survey of the theory of neighbouring extremals, special emphasis is
## Abstract Inβsitu temperature measurement is essential in CVD in order to control the temperature of the growing films. This is frequently achieved by optical pyrometry because it is a sensitive, convenient, and inexpensive technique that can be used in corrosive atmospheres. In this work, inβsit
