Motion type (or motion pattern) of a mechanism is defined as the set of all rigid motions achievable by the mechanism’s end-effector;the motion type of a parallel mechanism equals the intersection set of all subchain motion *** motion type of a non-instantaneous parallel mechanism locally agrees with a regular submanifold (or a Lie subgroup in particular) of the special Euclidean group SE(3).Based on submanifold germs of SE(3), we can define an equivalence relation and a partial order relation for both motion types and parallel mechanisms: two motion types are equivalent if and only if they agree on an open neighbor-hood around the identity element of SE(3);two motion types are comparable if and only if one is a submanifold of the other on an open neighborhood around the identity of SE(3).It is also possible to define equivalence relation and partial ordering on the col-lection of parallel *** this paper, we first study properties of the equivalence and partial order relation of both motion types and parallel mechanisms, then we discuss their application in type synthesis, mobility analysis and non-overconstrained ness realization of parallel mechanisms.

This paper develops both adaptive distributed dynamic state feedback control law and adaptive distributed measurement output feedback control law for heterogeneous discrete-time swarm systems with multiple *** convex hull formed by the leaders and the system matrix of leaders is estimated via an adaptive distributed containment *** estimations will feed the followers so that every follower can update the system matrix of the corresponding adaptive distributed containment observer and the system state of their *** followers cooperate with each other to achieve leader-follower consensus and thus solve the containment control problem over the *** results demonstrate the effectiveness and computational feasibility of the proposed control laws.

Dear editor,Recently,because of the high-efficiency requirements of modern industrial engineering,cyber-physical systems(CPSs) have received increasing attention. A CPS often contains a huge communication network,making it work more efficiently. Owing to CPSs’ high efficiency in industrial engineering,they have been extensively studied and explored in practice.
