Using the adaptive blockset for simulation and rapid prototyping

The paper presents the design considerations and implementation aspects of the adaptive blockset for Simulink which has been developed in a prototype implementation. The basics of indirect adaptive controllers are summarized. The concept behind the adaptive blockset for Simulink is to bridge the gap between simulation and prototype controller implementation. This is done using the code generation capabilities of real time workshop in combination with C-function blocks for adaptive control in Simulink. In the paper the design of each group of blocks normally found in adaptive controllers is outlined. The block types include: identification, controller design, controller and state variable filter. The use of the adaptive blockset is demonstrated using a simple laboratory setup. Both the use of the blockset for simulation and for rapid prototyping of a real-time controller are shown.
