A novel neural network sliding mode control based on multicommunity bidirectional drive collaborative search algorithm (M-CBDCS) is proposed to design a flight controller for performing the attitude tracking control of a quad tilt rotors aircraft (QTRA). Firstly. the attitude dynamic model of the QTRA concerning propeller tension. channel arm. https://macorners.shop/product-category/sweatshirt-and-sweatpants-set/
