Abstract:Based on the synchronous language elements introduced in Modelica 3.3; a library is described to utilize the new features in a convenient way for graphical model definition of sampled data systems. The library has elements to define periodic; non-periodic and event clocks that trigger elements to sample; sub-sample or super-sample partitions synchronously. Optionally; quantization effects; computational delay or noise can be simulated. Continuous-time equations can be automatically discretized and utilized in a sampled data system. This is demonstrated by utilizing the inverse of a nonlinear plant model in the feed forward path of a discrete controller of a mixing unit.
