A simple display-interactive system for process control using a small computer is presented which is based on conventional digital filter design methods and accuracy considerations. The system permits gain, lead, and lag-lead compensation of a two-real-pole plant with position offset. The program, written for the PDP-12, allows the user much flexibility in sampling and displaying the step, responses and choosing the compensator parameters. There is also provision for evaluating the system performance (peak time, maximum overshoot, and position offset). This flexibility is provided by organization of the program into large subroutine packages, e.g. graphic display, fixed-point two-decimal-place and double-precision (24-bit) fractional arithmetic routines, compensator difference equations, etc. Discussed are theoretical and practical aspects of the system design and implementation, sources of error, overall structure of the program, including a general flowchart, experimental results, the limits imposed on the program by the computing facilities used, and some suggestions concerning possible extensions of the system. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

A set of equations is introduced which describes the inhibitory interaction between the receptors in the eye of the horse-shoe crab, Limulus. The terms primary inhibition field, and inhibition field are defined, and the results of a digital computer study of their interdependence with respect to size and to the type of k[subscript i,j] and t[subscript i,j] functions employed are given. It is concluded that a large receptor array can be simulated by solving the set of equations for the output of the central receptor in much smaller sub-arrays. If the sub-arrays are chosen so as to cover the large array, then the resulting set of central receptor outputs provides a good approximation to the output of the large array. A device which simulates a large receptor array by repetitive solution of the set of equations for 9×9 sub-arrays is described. Various switching arrangements which reduce the complexity of the device are detailed. The circuit diagrams for all the required elements are given. In order to evaluate the possible utility of the device as a tool in pattern recognition studies, the output from the device for certain simple patterns was simulated on the digital computer. The results of this study are given, and some possible applications to the field of pattern recognition are mentioned. It is pointed out that the design of the device makes it a versatile instrument for simulating various types of receptor arrays. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
