fcis-9423	Shao, Keyong; Pan, Yuda	Design of Preset Performance Reverse Step Attitude Controller for Four-rotor UAV	2023	5	.pdf	application/pdf	4200	217	62	Keywords: UAV Attitude Angle Control; Extended State Observer; Preset Performance Control; Backstepping Control. For equation (25), where, 1X̂ , 2X̂ and 3X̂ respectively represent four the estimated value of attitude Angle, attitude Angle rate and lumped interference of the rotor UAV 3I are represented by the unit matrix 3 3 , where 0 represents the zero matrix of appropriate dimension, H is the observer gain matrix, w is the bandwidth of the linear expanded state observer and satisfies 0w  .	cache/fcis-9423.pdf	txt/fcis-9423.txt
