Studies on open source real time operating systems: For vehicle suspension control

Abstract

Studying the TIMELINESS of PERIODIC tasks of real time operating systems available in open source, to determine the reliability and efficiency of the systems for implementing them in suspension control of ground vehicles. We take several operating systems which are open source and are available to the public through GNU license (ex: Linux). The Kernels, which are the building blocks of the operating systems which connect hardware and software, are patched using selective real time patches which makes the operating system real time. This is done in order to unlock real time capabilities such as unbounded latencies and real time priorities. These operating systems are tested for their efficiency and timeliness. The results are compared with the test logs of non-real time operating system. These kernels are then cross compiled and built for ARM architecture. This kernel is then applied to an embedded system which is then tested using the same afore mentioned tests. The results are logged and analyzed.
