Stability Derivatives - Control Derivatives

Control Derivatives

Deflection of control surfaces modifies the pressure distribution over the vehicle, and these are dealt with by including perturbations in forces and moments due to control deflection. The fin deflection is normally denoted (zeta). Including these terms, the equations of motion become:

Including the control derivatives enables the response of the vehicle to be studied, and the equations of motion used to design the autopilot.

Famous quotes containing the word control:

    Could it not be that just at the moment masculinity has brought us to the brink of nuclear destruction or ecological suicide, women are beginning to rise in response to the Mother’s call to save her planet and create instead the next stage of evolution? Can our revolution mean anything else than the reversion of social and economic control to Her representatives among Womankind, and the resumption of Her worship on the face of the Earth? Do we dare demand less?
    Jane Alpert (b. 1947)
