Modeling Carrier Motion Using Power Spectrum Models to Realistically Reflect Aircraft Carrier Movement

The study establishes that aircraft carrier motion at sea exhibits stationary random process characteristics, prompting the implementation of power spectrum models for realistic motion simulation. The research involves precise analysis of deck motion effects on ideal touchdown points and implements fuzzy logic control for carrier-based aircraft altitude regulation. Following the layered architecture of automatic carrier landing systems, the project systematically designs and validates three core components: the automatic flight control system (modeled using state-space representations), approach power compensation system (implemented with transfer function blocks), and deck motion compensator (designed with spectral analysis algorithms). Through comprehensive MATLAB/Simulink modeling, the complete system undergoes rigorous simulation testing. The developed fuzzy PID controller incorporates real-time parameter adjustment mechanisms using membership functions and rule bases, with MATLAB simulations confirming substantial improvements in landing performance metrics while preserving core design principles.
