In order to ensure the stability and safety of the on-orbit service spacecraft attitude motion, the attitude tracking system often enhances the strict state performance guaranteed design requirements. The performance guaranteed control algorithms provide sufficient state-constrained design methods for closed-loop systems. For spacecraft attitude control systems, actuators usually have limited response capabilities to control command signals, such as maximum output torques, rate, magnitude/amplitude, and bandwidth limitations. In this chapter, considering the control input command signal regulation, the performance guaranteed control algorithm based on the command filter technique is proposed. The command filter is configured between the theoretical control input and the actual control input. Before the theoretical control signal is transmitted to the actuator, it needs to be filtered by the command filter. This filter can constrain the signal’s rate, magnitude/amplitude, and bandwidth, smooth the command signals and avoid peak interference. In this way, the response of the actuators is closer to the theoretical design. The spacecraft attitude tracking closed-loop system can not only meet the performance guaranteed constraints but also obtain acceptable control inputs within the reasonable range. The spacecraft attitude tracking closed-loop system is asymptotically stable and has strong disturbance suppression ability. The proposed controller’s rationality and effectiveness are further demonstrated through the proof and simulation.
