A nonlinear sampled data feedback control system employing pulsed thrust position control

This thesis shows that reaction jet thrust pulses, each of constant amplitude and time duration, in conjunction with sampled data error information can provide satisfactory position and/or attitude control for space vehicles. Incremental phase-plane analysis of the system yields a technique for determining system response and suggests a means of compensation. Control system response for the vehicle under the influence of external forces is shown to be satisfactory by digital computer simulation --Abstract, page ii
