A Sampled Data Production Controller Using Predictive Error Correction.
Abstract
The objective of this research project is to study the implementation of a predictive state variable sampled data controller for a large scale production system. Although this research will be directed specifically towardds the Small Caliber Ammunition Modernization Program (SCAMP), the procedures developed will be applicable to any production system which can be modeled as a sampled data control system. To achieve this objective, (1) the ammunition production plant is modeled in state variable form, (2) the results of (1) are solved as discrete difference equations as a function of a discrete time interval and initial conditions, (3) the solution of (2) with the present state of (1) as the initial conditions becomes the predictive controller for the process, and (4) extensive logic control circuitry is developed to aid the digital computer in the control of the system. The result of the research shows that the predictive controller is very effective in increasing the stability of the sampled data controller for sample times which would lead to oscillations in systems which do not use predictive control.
