Computer-Aided Engineering Environment for Controlled Mechanical Systems
Abstract
A computer-aided engineering environment for the design and analysis of computer controlled mechanical systems is defined, and a prototype environment is demonstrated. The overall integrated environment includes systems for 3D geometric modeling and animation, multibody system dynamics, finite element analysis, and control system design. The integration of a multibody system dynamics program IMP with the control system design program MATRIXx is demonstrated. Transfer functions from the multibody system model, together with mathematical models of any electrical, pneumatic, and hydraulic components, are used in MATRIXx for control system synthesis. The controller architecture and parameters are specified in block diagram form and converted to real-time program through an automatic code generator in MATRIXx. This program is downloaded to microprocessor for controlling the actual, physical plant; In the computer-aided engineering environment of this report, the controller program with any nonmechanical component models included is combined with the original IMP nonlinear mechanical system model. The dynamic response of this complete system is studied to verify the controller design for this nonlinear, more realistic mechanical model. (kr)
