The investigations reported are concerned with the Application of logic-networks, pattern recognition concepts and function-approximation methods to control problems. These techniques are used in approximating an implicitly defined adaptive control law by a fixed function of measurements of the plant motion. The implicit control law is determined off-line for a set of sample points which are representative of possible measurements made on the plant and a function is determined which satisfactorily maps the sample points into the desired control. The function obtained is then used as the closed-loop control law. Section II of this report reviews the way in which logic-networks may be used to mechanize controllers. Section III shows how an adaptive control problem yields an implicitly defined control function. Section IV applies the concept of a fixed-function approximation of an implicit control law to design of a time-optimal pitch-rate controller for the F101 aircraft. (Author)
