H2-clustering of closed-loop consensus networks under a class of LQR design

Nan Xue, Aranya Chakrabortty
2016 2016 American Control Conference (ACC)  
Then, a r-dimensional reduced-order network is created by imposing a projection matrix P on the n-node open-loop network, and a reduced-order r-dimensional LQR controller is constructed.  ...  The problem, therefore, is to find a grouping strategy or P that will minimize the difference between the closed-loop transfer matrix of the original network with the full-order controller and that with  ...  The closed-loop transfer matrix (TM) of the network output from a disturbance input under this full-order LQR controller is defined as the benchmark TM.  ...

Distributed Design for Decentralized Control using Chordal Decomposition and ADMM [article]

Yang Zheng, Maryam Kamgarpour, Aivar Sootla, Antonis Papachristodoulou
2019 arXiv   pre-print
We propose a distributed design method for decentralized control by exploiting the underlying sparsity properties of the problem.  ...  We first apply a classical parameterization technique to restrict the optimal decentralized control into a convex problem that inherits the sparsity pattern of the original problem.  ...  The distributed design framework of [10] has been used to discuss the best closed-loop performance achievable by distributed design strategies for a class of fully actuated discrete-time systems [11  ...

Robot grasping by exploiting compliance and environmental constraints

The complexity of robot grasping stems from the fact that any solution comprises various components: Hand design, control, perception, and planning all affect the success of a grasp.  ...  They are situated in an environmental context: on a table, in a shelf, inside a drawer, etc.  ...  For the first two tasks, we compare our method to the following baselines: • Hand designed baseline: A controller with a hand-designed open loop policy.  ...
