Constraint Procedures for Computer Aided Design

open access: closedIFAC Proceedings Volumes, 2000
Abstract The nature of creative design makes it impossible to fully define all the design requirements before the activity commences. The process is goal directed in which an understanding of the problems emerge as the activity advances. This aspect of design is thus considered to be aligned to problem solving strategies, in which search techniques ...

Computer Aided Design of Multi-Level Systems with Prescribed Structure and Control Constraints

open access: closedIFAC Proceedings Volumes, 1979
Abstract In this paper two hierarchical control algorithms (P and PI) for linear discrete-time interconnected systems are presented. At the first level minimization of local performance indexes is done and at the level 2 - coordination, based on a gradient procedure. The algorithms presented satisfy constraints impased on the control components. They

Constraint-Based Computer-Aided Design

open access: closedJournal of Computing and Information Science in Engineering, 2005
Computer-aided design (CAD) systems have become parametric, basing shape design on constraints and design feature operations. We review the development of constraint-based parametric CAD, explaining some of the foundational issues as well as giving an outlook on possible future directions of development.

Computer Aided Stabilator Design Including Aeroelastic Constraints

open access: closedJournal of Aircraft, 1971
A computerized direct optimization procedure has been developed to aid in the design of an aircraft all-moveable stabilator. The procedure systematically evaluates a set of design variables so that the near optimum stabilator is synthesized from input nondimensional geometry and material characteristics to satisfy design constraints of performance ...

Geometric Constraint Solving in Parametric Computer-Aided Design

open access: closedJournal of Computing and Information Science in Engineering, 2011
With parametric computer-aided design (CAD) software, designers can create geometric models that are easily updated (within limits) by modifying the values of controlling parameters. These numeric and non-numeric parameters control the geometry in two ways: parametric operations and geometric constraint solving.
