A computer-aided engineering (CAE) environment for the design and analysis of computer-controlled multibody systems is defined, and a prototype environment is demonstrated in this paper. The overall integrated environment includes systems for three-dimensional geometric modeling and animation, multibody system dynamics, finite element analysis, and control system design. In this paper, 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 a real-time program through an automatic code generator in MATRIXx. This program is downloaded to a microprocessor for controlling the actual, physical plant. In the CAE environment of this paper, the controller program, with any non-mechanical component models included, is combined with the original IMP non-linear mechanical system model. The dynamic response of this complete system is studied to verify the controller design for this non-linear, more realistic mechanical model. |
