Abstract: A system for and method of determining an input command profile for substantially any dynamic system that can be modeled as a linear system, the input command profile for transitioning an output of the dynamic system from one state to another state. The present invention involves identifying characteristics of the dynamic system, selecting a command profile which defines an input to the dynamic system based on the identified characteristics, wherein the command profile comprises one or more pulses which rise and fall at switch times, imposing a plurality of constraints on the dynamic system, at least one of the constraints being defined in terms of the switch times, and determining the switch times for the input to the dynamic system based on the command profile and the plurality of constraints.

Abstract: The system described herein determines an input command profile for a dynamic system that can be modeled as a linear system, the input command profile for transitioning an output of the dynamic system from one point to another point. The system identifies characteristics of the dynamic system, and then selects a command profile which defines an input to the dynamic system based on the identified characteristics. The command profile comprises one or more pulses which rise and fall at switch times, and the command profile is useable with substantially any dynamic system that can be modeled as a linear system. The system then imposes a plurality of constraints on the dynamic system, at least one of the constraints being defined in terms of the switch times, and determines the switch times for the input to the dynamic system based on the command profile and the plurality of constraints.

Abstract: A digitally programmed computer takes as input a schematic of a mechanical system and specification of the overall system including utility and cost functions and provides as output catalog numbers from a pre-defined set for the optimal selection of working components implementing the design. The preferred embodiment provides the user with a high level symbolic language in which to interact with the programmed computer. The process of compilation or transformation from a high level language to a low level description, is based on a formalization of quantitative inferences about hierarchically organized sets of mechanical components and operating conditions. This method allows design compilation without the exhaustive enumeration of alternatives.

Abstract: A sequence of impulses is determined which eliminates unwanted dynamics of a dynamic system. This impulse sequence is convolved with an arbitrary command input to drive the dynamic system to an output with a minimum of unwanted dynamics. The input sequence is time optimal in that it constitutes the shortest possible command input that results in no unwanted dynamics of the system subject to robustness and implementation constraints. The preshaping technique is robust under system parameter uncertainty and may be applied to both open and closed loop syThe Government has rights in this invention pursuant to Grant Number N00014-86-K-0685 awarded by the Department of the Navy.
