Non-Linear Space Stabilization System Acquiring Minimum Rate in Minimum Time With Minimum Energy

The efficient use of fuel and the rapid damping of disturbances are desirable in control systems. A system utilizing a derived control equation and modulation techniques is presented in Section I which meets these efficiency and damping requirements. Section II describes a second system in which displacement and rate-logic switching are separated to eliminate the hardware uncertainties that prove detrimental to switching line summing techniques.
