Abstract

Safety is a fundamental concept in engineering problems, such as automotive applications. Critical control systems must establish stability/performance criteria as well as comply with safety restrictions. Recently, the concept of barrier control function (CBF) has been considered as an efficient option to guarantee safety in control systems, in which safety restrictions are specified in terms the forward invariance of a safe set mapped by a CBF. However, for systems with relative degrees greater than one, the classic CBF approach cannot be used, and adaptations are necessary. One of the common ways to solve this issue is to define exponential CBFs (ECBFs). As CBFs are model-based, another important factor is to ensure robustness in the restrictions imposed by the barrier functions, which in this work will be tackled defining a sliding mode CBF (SMCBF) that, despite ensuring robustness, allows application in systems with relative degrees greater than one. Therefore, with the development of this research project it is expected the production of scientific and technological knowledge, which will be shaped by the development of methods, techniques and tools that allow the design and validation of automotive safe control systems.
