Abstract
In this chapter we extend the compositional approach from stability analysis to certifying performance and safety. Performance is defined as a desired dissipativity property for the interconnection, such as a prescribed gain from a disturbance input to a performance output. A storage function for the interconnection is synthesized as a weighted sum of subsystem storage functions and the weights are left as decision variables in a linear matrix inequality. Next we address the safety problem where the goal is to guarantee that trajectories starting in a prescribed set do not intersect a given unsafe set under a set of admissible disturbances. This time a weighted sum of subsystem storage functions serves as a barrier function for the interconnection.
