In this paper we propose a novel mission control strategy for a group of agents to locate an unknown source, represented as maximum of a scalar field, and to track a specified level curve. We propose a distributed control scheme based on hierarchy formation and reduced topology. Without prior knowledge of the field, the agents, equipped with local sensors, navigate in ℝp using an estimated gradient...
The notion of output-feedback controlled-invariant sets is extended from LTI systems to systems with linear parameter-varying state transition matrix. A theorem is presented that can be used to verify whether a given polytope can be made invariant under output-feedback. The theorem also provides the constraints a control input has to fulfill to make the candidate set invariant. Predictive output-feedback...
