The first model represents wind forces acting on the antenna dish, and it closely represents actual wind action. The second model represents wind gusts as torque disturbances applied to the antenna drives. The third model represents gusts acting at the antenna rate input. A wind filter introduced in this article makes the wind gusts of the third model equivalent to the gusts of the second model. The third model is of recent interest, since it is applicable to the currently developed models of the antenna closed-loop systems. Simulink models of the 34-m and 70-m antennas’ closed-loop systems were developed to simulate antenna servo errors in wind gusts. The article shows that for the 34-m and 70-m antennas all three models give similar results, and that the results are comparable to the field measurements of the servo errors taken in wind.
