Summary:A pulse modulation scheme based on two modulation curves is proposed for applications in spacecraft attitude control using thrusters which may be subject to switching restrictions. These constraints are taken into account explicitly during the design of the modulation scheme which can implement arbitrary bounded functions between constant modulator input and averaged modulator output. Ein Pulsmodulationsschema wird vorgestellt für die Lageregelung mit schaltenden Düsen-Stellgliedern und vorgeschriebenen Schaltrestriktionen. Das Modulationsschema basiert auf zwei Modulationskennlinien, bei deren Entwurf die Schaltrestriktionen ausdrücklich berücksichtigt werden. Beliebige beschränkte Funktionen können so zwischen konstantem Modulatoreingang und gemitteltem Modulatorausgang realisiert werden.
