这封信介绍了积分控制障碍函数(I-CBF)作为一种手段,使非线性系统的安全关键积分控制。重要的是,I-CBF允许在单个框架中对状态约束和输入边界进行整体编码。我们证明了这一点,通过将它们应用到一个动态定义的跟踪控制器,从而执行安全的状态和输入通过一个微创I-CBF控制器框架作为一个二次规划。
This letter introduces integral control barrier functions (I-CBFs) as a means to enable the safety-critical integral control of nonlinear systems. Importantly, I-CBFs allow for the holistic encoding of both state constraints and input bounds in a single framework. We demonstrate this by applying them to a dynamically defined tracking controller, thereby enforcing safety in state and input through a minimally invasive I-CBF controller framed as a quadratic program.
