The actuators perform at least one primary task and at least one non-primary task, including: a) determining a pseudo-control command up∈p′ based on a physical model of the system, which command represents the torques (L, M, N) and a total thrust force (F) acting on the system, b) determining a control matrix D, D∈p′×k according to up=Du, where u1=D−1upu1∈k represents a control command for the actuators to perform the primary task, c) projecting the non-primary task into the null space N(D) of the primary task, so that Du2=0 if u2u2∈k represents a control command for the actuators to perform the non-primary task, and d) providing the control commands from b) and c) to the actuators. In this way, the solution of the primary task is not adversely affected by the non-primary task or its solution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and control unit for controlling an overdetermined system, system and aircraft","description":"A method for controlling an overdetermined system with multiple actuators, for example an aircraft (1) with multiple propulsion units (3).
