Filtering Based Multiple-Model Control for Satellites in the Presence of Actuation Sign Errors
This paper presents a new filtering based multiple-model control scheme for satellite attitude tracking control in the presence of sign errors in actuator response.As a result of a software or hardware fault,such actuation sign errors which are uncertain in occurring time instants and patterns may lead to the loss of satellites.The control design employs two steps: first,a bank of control laws are developed,each of which can ensure the system stability and asymptotic attitude tracking properties when the system operates under the corresponding actuation sign pattern; then a control switching mechanism is set up to find out the most appreciate control law as the applied control signal with a minimal performance cost index function.The used performance cost functions are calculated from the estimation errors generated by using a stable filter.Simulation results for a satellite with four reaction wheels are presented to demonstrate the effectiveness of the proposed multiple-model control scheme.
