Abstract:
This paper presents a seamless low-cost Rapid Control Prototyping (RCP) development platform, LoRra for short, based on the open source software Scilab / Xcos. The model-based, verification-oriented RCP development process is introduced to master the increasing system complexity in ever-shortening development cycles. Within this process Model-in-the-loop (MiL)-, Software-in-the-Loop (SiL)-, and Hardware-in-the-Loop (HiL)-simulations are performed for testing and optimization. Based on requirements derived from the process, the concept of the LoRra platform is developed first. It contains model libraries, a code generator, a real-time interface, real-time hardware and a human-machine interface for measurement and calibration tasks. Subsequently, the design of each component will be discussed. Finally, a first validation and optimization of the platform is carried out by using the state of charge estimation for lithium-ion batteries.
