Abstract : Automatically controlled systems frequently employ proportional plus integral devices as the controller in the closed loop. The determination of the optimum values of the coefficients of the proportional and integral terms is normally accomplished by trial and error procedures. In an effort to obviate this procedure, a method was developed to compute the optimum values of gain and integration constant of a conventional proportional plus integral controller using an analog computer operating iteratively and in fast time. The results of this computation were applied directly to the settings of a controller in a closed loop system operating in real time. The speed of the optimization process was such that the optimum controller settings were determined for a disturbance after the disturbance had taken place but before the process had responded to any significant degree.
