A method of operating an actuator system (1) having a number k, k∈, of actuators (2), in particular individual propulsion units of an MAV-VTOL aircraft (10), in particular electrically powered actuators, wherein a desired control command up∈m, m∈, for controlling the actuator system (1) is allocated to real actuator commands u∈k, k∈, by using a weighted allocation matrix D (W), from an equation u=D−1(W)up, wherein D−1(W) is an inverse of the weighted allocation matrix, and the real actuator commands u are applied for controlling the actuators (2). The method includes determining a characterizing value u* from the real actuator commands u; determining, at least for some of the actuators (2), preferably for all of the actuators (2), a deviation ei, i=1, 2, . . . , k of a respective actuator command ui, i=1, 2, . . . , k from said characterizing value u*; determining, at least for some of the actuators (2), preferably for all of the actuators (2), a weight wi, i=1, 2, . . . , k for a given actuator (2) as a function wi(ei), i=1, 2, . . . , k of said deviation ei; and using the weights wi for determining said weighted allocation matrix D(W). An actuator system which is operated according to this method and an aircraft with a plurality of propulsion units as a specific use case are also provided.
