First, a detailed computer simulation model of AFIT's SIMSAT satellite simulator was constructed. Control strategies were developed to enable the system to perform large-angle, 3-axis slewing maneuvers using a combination of both thrusters and reaction wheels. To handle the non-linear model, a State Dependent Riccati Equation controller was programmed and successfully controlled the computer-modeled satellite for any given slewing maneuver. A simpler PD controller was then programmed and demonstrated on the computer simulation of SIMSAT, using a combination of thruster and reaction wheel control inputs for large-angle single axis maneuvers and for small angles using three-axis control. There was good agreement between the experimentally obtained maneuver results and those produced with the computer simulation model for the single-axis case. Lastly, the trade-off between settling time and thruster fuel is discussed, as well as the variation of gains required to achieve maximum performance for a desired slew.\u003c\/p\u003e","brand":"Mia Karts","offers":[{"title":"Default Title","offer_id":51960690049312,"sku":"NEW128833270X","price":21.54,"currency_code":"USD","in_stock":false}],"url":"https:\/\/miakarts.com\/products\/hybrid-control-strategies-for-rapid-large-angle-satellite-slew-maneuvers-128833270x","provider":"Miakarts Books","version":"1.0","type":"link"}
