In order to solve the difficult problem of low energy state recovery caused by the speed neutral static stability of modern fly-by-wire civil aircraft, a design method of low energy recovery control law was studied. First of all, based on the principle of total energy control, the speed-height decoupling control method was studied according to the characteristics of the civil aircraft instrument landing system (ILS). Secondly, the recovery control laws for the low kinetic energy state and the low potential energy state were designed respectively, and the relationship between them and the original control law of the aircraft was clarified. Finally, a certain type of dual-engine branch line telex airliner was taken as an example to verify the effectiveness of the low energy recovery control law. It is shown that the control law was helpful to reduce the workload of the pilot and improve the recovery efficiency. The research results can provide a theoretical reference for the control law design of low energy recovery.
