Embodiment Construction
[0075] The drawings constituting a part of the present invention are used to provide a further understanding of the present invention, and the schematic embodiments and descriptions of the present invention are used to explain the present invention, and do not constitute an improper limitation of the present invention.
[0076] Such as figure 1 As shown, the present embodiment provides a method for suppressing ship wake disturbance based on direct lift control, which specifically includes the following steps:
[0077] Step 1: Based on the track coordinate system and considering the influence of the ship's wake, a nonlinear model of the longitudinal motion of the carrier-based aircraft is established.
[0078] Step 2: For the nonlinear model in step 1, establish a second-order h-γ cascade active disturbance rejection controller, use the extended state observer (ESO) to observe the altitude state variable and the glide angle state variable respectively, and form a state error fe...
