❁It is a kind of robust control method, and its design core is to make the closed-loop system passive. Its core is to start from the perspective of energy. Its physical concept is very intuitive and easy to be accepted by engineers. It has a wide range of applications in many actual physical systems.

❁Cyber-physical systems are multi-dimensional and complex systems that integrates computing, network and physical environment.

❁Proposes a novel dynamic stepsize selection approach for the distributed gradient algorithm and develops the associated distributed gradient algorithms for synchronous and asynchronous gossip-like communication protocol.

❁Differently from the existing distributed algorithms whose diminishing or fixed stepsizes are determined before the algorithm is run, the proposed algorithms use dynamic stepsizes that rely on the time-varying estimates of the optimal function values generated at each iteration during the algorithms.

❁The dynamic stepsize needs no knowledge of the global information on the network or the objective functions, which makes the proposed algorithms more applicable compared to distributed algorithms with fixed stepsizes.
