its convenient use, no leakage, and conforming to the requirements of missile-borne
energy unit, has developed from small missile to large missile, especially
ship-borne air defense missile. The control surface differential schemes are mostly
electric differential schemes, and mechanical differential schemes are seldom used.
Hydraulic steering gear is mostly used in the United States, air-conditioned steering
gear in the Soviet Union and electric steering gear in France. One is to provide
separate energy for the control execution system, and the other is to make comprehensive use of the auxiliary energy of the whole missile.
(2) Control Trajectory Working Condition
In order to design the execution system and its energy economically and rationally,
it is necessary to study the working conditions of the system comprehensively from
two aspects: control signal flow and energy power flow. Its main contents include
the control surface deflection motion law and the corresponding load moment
change law; the execution system dynamic characteristics and aerodynamic elasticity; the law of seeker antenna angle change and corresponding load moment
change; the law of missile-borne power grid load current, frequency, voltage
change with ballistic. These parameters are all functions of trajectory control.
Therefore, comprehensive research involves general, guidance, control, aerodynamics, load, aeroelasticity and structure, and other related specialties. Only by
vigorous coordination and close cooperation can it work. The numerical calculation
can be used in the study of working conditions, and it can be combined with missile
flight test if necessary.
(3) General Argumentation and Systematic Analysis
The necessity demonstration of missile overall scheme is an important prerequisite
for the technical feasibility analysis of the execution system, and the technical
feasibility analysis of the execution system is a reliable guarantee for the implementation of the overall technical requirements of the missile. They should work
together and participate crosswise. It allows the system to put forward
“counter-requirements” and “counter-suggestions” to the overall scheme, and also
allows the overall scheme to modify the overall requirements and propose technical
issues to the system. Only by organic combination and feedback control design
method can the best and most applicable system scheme be obtained.

Combining with the design method of air defense missile control actuation system,
the classification forms of missile-borne auxiliary energy and primary energy of air
defense missile are discussed, and typical examples are analyzed. This section
elaborates on a series of important issues of missile energy, such as unit and
diversity, separate and comprehensive utilization, source and common source,
