Query: Finite-time enclosing control for multiple moving targets: a continuous
  estimator approach   This work addresses the finite-time enclosing control problem where a set of
followers are deployed to encircle and rotate around multiple moving targets
with a predefined spacing pattern in finite time. A novel distributed and
continuous estimator is firstly proposed to track the geometric center of
targets in finite time using only local information for every follower. Then a
pair of decentralized control laws for both the relative distance and included
angle, respectively, are designed to achieve the desired spacing pattern in
finite time based on the output of the proposed estimator. Through both
theoretical analysis and simulation validation, we show that the proposed
estimator is continuous and therefore can avoid dithering control output while
still inheriting the merit of finite-time convergence. The steady errors of the
estimator and the enclosing controller are guaranteed to converge to some
bounded and adjustable regions around zero.
