Abstract : This study develops a computer program for interactive execution to aid in the design of Command Generator Tracker control systems employing Proportional Plus Integral inner loop controllers based on the integral of the regulation error and Kalman Filters for state estimation (CGT/PI/KF controllers). Sampled-data controller designs are based upon the Linear system model, Quadratic cost, and Gaussian noise process assumptions of optimal control theory. The report develops the CGT/PI/KF controller theory with the PI controller portion based upon the integral of the regulation error. Following a brief description of the computer program developed, results of applying it to an example aircraft-related controller design problem is presented. The CGT/PI/KF controller is found to be a technique particularly well suited to the aircraft control design problem but is a technique that may be applied to any general controller problem fitting the design criteria. Use of the computer program is fully documented in the appendices of the report. Included are a brief 'Programmer's Manual' a complete 'User's Manual', and a program listing. These pertain to the computer program as implemented on a CDC CYBER computer system. (Author)
