US Patent 7890310 Method for analysis of control systems

The present invention provides a framework to let users systematically analyze, and design controllers for, complex non-linear dynamic systems modeled in a block diagram environment. By extracting linearized models from non-linear plant models (block diagrams), users can use one or more control design and tuning methodologies available for linear systems. Complex side effects, such as cross-coupling and exogenous disturbances, are viewable and can be dealt with in real-time during a design. The results of a design are automatically implemented in a block diagram.
