A method of manipulating a block diagram model with a plurality of graphical modeling components by defining an open loop anywhere on the block diagram model is provided. Graphical modeling components in series with the open loop may be automatically recognized and a plurality of parameters of the graphical modeling components in series with the open loop may be displayed on a display device. A user may simultaneously tune the parameters of the graphical modeling components in series with the open loop. Factorization points breaking the block diagram model in two disconnected parts may be identified in the block diagram model. A virtual graphical model may be generated by replacing a pattern of the graphical modeling components between two factorization points with a single graphical modeling component representing the pattern.

Modeling of control systems with open-loop representations and factorization of components

The present invention provides a method of modifying the behavior of a modeled system from a graphical representation of the behavior of the system. Given a graphical representation of the behavior of a modeled system, one or more bounds may be selected for the behavior on the graphical representation. The necessary parameters for the modeled system are then determined for producing the desired behavior based on the selected bounds for the behavior.
