In Chap.  2 , we introduced a distributed fencing controller via neighboring angle repulsion to achieve cooperative fencing of a constant-speed target, establishing the fundamental task of fencing. This chapter considers the more complex fencing problem that ensures evenly rotational formation during the fencing process, which is distinct from the previous fencing work in Chap.  2 . Moreover, it also considers the disturbances induced by intermittent topologies during the fencing process. A distributed cooperative fencing control algorithm via input-to-state stability is proposed, which aims to solve the more complex fencing problem with evenly rotational formation. In what follows, we will introduce the related background.
