  We apply a measurement-based closed-loop control scheme to the dissipative
Lipkin-Meshkov-Glick model. Specifically, we use the Wiseman-Milburn feedback
master equation to control its quantum phase transition.For the steady state
properties of the Lipkin-Meshkov-Glick system under feedback we show that the
considered control scheme changes the critical point of the phase transition.
Finite-size corrections blur these signatures in operator expectation values
but entanglement measures such as concurrence can be used to locate the
transition point more precisely. We find that with feedback, the position of
the critical point can be shifted to smaller spin-spin interactions, which is
potentially useful for setups with limited control on these.
