CONTROL WITH TERMINAL INVARIANCE TO DISTURBANCES AND MINIMAL EXPENDITURES OF ENERGY. STABILIZATION OF SV ATMOSPHERIC FLIGHT
Extending the paper on terminal invariance [1], we present here the method of control parameter adjustment, which makes it possible to satisfy constraints at minimal expenditures of energy in the presence of uncertain disturbances. Based on the data [2, 3], this method can be used when solving problems on stabilization of programmed longitudinal motion of spacecraft atmospheric descent. Making use of the numerical example, we show application of data [1] for stabilization of a spacecrafts angular programmed motion and realization of terminal invariance to uncertain external and parametrical disturbances; the so-obtained data are in complete agreement with those on process stabilization simulated in the MATLAB programming system.
