Title Cruise missile simple flight control system research
Abstract
Cruise missile flight control system is a complicated and huge system. In
view of the longitudinal motion model of the cruise missile, this paper
carried out the research on simple cruise missile flight control system. Do
the following work: a) understand the cruise missile motion process,
establish the cruise missile’s mathematical model of longitudinal motion,
establish normal overload as a control system to control the quantity of the
model , convert the mathematical model into the Simulink model and allow it
to run properly; b) Using the theory of PID control and sliding mode variable
structure control theory, design simple flight control system, calculate
control parameter, analysis and research, try to make the system stable. Both
in the presence of disturbance, analyze their robustness of the system, and
make a comparative study; c) The Terminal adaptive control theory is
introduced into sliding mode variable structure control, by using the method
of adaptive sliding mode control, flight controller is designed to make the
control performance is further optimized. Through the Simulink simulation,
it can be seen from the simulation results that the mathematical model is
correct, the controller design is reasonable, the control effect is good and
the design of the feasibility of cruise missile flight control system is verified.
