“…With the development of the space camera technology, highresolution imaging under attitude maneuver has been focused on recently [1][2][3]. However, the imaging results could be declined seriously by the huge flexible solar array and the vibration-generating devices [4][5][6]. For example, the huge flexible solar array could induce pointing overshoot, the high-frequent vibration could induce the imaging blurring, and the low-frequent vibration could induce the imaging warping [7,8].…”

In order to achieve the attitude maneuver performance of the noncontact close-proximity formation satellite architecture, this paper presents a compound control strategy with variable-parameter sliding mode control and disturbance observer-based feedforward compensation. Firstly, the variable-parameter sliding mode control is proposed to guarantee the attitude maneuver performance of the payload module. Secondly, the collision avoiding control with disturbance observer-based feedforward compensation is proposed to guarantee the synchronization of the two separated modules within the small air clearance constraint of the noncontact Lorentz actuator. Finally, a physical air-floating platform is established to verify the effectiveness of the proposed approach.

“…With the trend of larger expansion in dimensions, the deployable appendages of the spacecraft, such as the solar array, the antenna, and the manipulator, possess remarkable flexibility in a fully deployed state [1,2]. The ultralow natural frequency of the large-scale flexible appendage f n is the main reason for slow vibration attenuation.…”

Envelope-Based Variable-Gain Control Strategy for Vibration Suppression of Solar Array Using Reaction Wheel Actuator

The orbital operation of spacecraft can excite the long-drawn and low-frequency vibration of the solar array, which is prone to affecting the task execution of the system. To address this issue, an envelope-based variable-gain control strategy is proposed to suppress vibration of the solar array using the reaction wheel (RW) actuator. The RW actuator is individually mounted on the solar array to provide reaction torque through the speed change of its rotor. The governing equation of motion of the solar array actuated by a RW actuator is deduced with the state space representation. The control relation between the measured bending moment and the rotational speed of the RW actuator with the constant-gain coefficient is firstly developed and demonstrated in numerical simulation. Changing the gain coefficient to be inversely proportional to the envelope function of vibration, a variable-gain control strategy is proposed to improve the damping effect of the RW actuator. Simulation results show that the vibration suppression performance of the RW actuator is improved compared to the constant-gain control. As the actual on-orbit natural frequency of the solar array is not always exactly known, the robustness of the control system is analyzed for the deviation between the estimated and the actual natural frequency values. The proposed variable-gain control is also experimentally verified using a simplified elastic plate model. Experimental results indicate that the vibration attenuation time is decreased to 29.1% and 50.22% compared to the uncontrolled and the constant-gain controlled states, respectively.

“…Active Vibration Control (AVC) technologies are widely used to suppress vibrations of flexible structures, for example, buildings (Cha et al, 2013), large space structures (Wang et al, 2020), ultra-precision motion systems (Huang et al, 2018), and active antennas (Liu et al, 2017). The performance of AVC depends on not only controller design but also sensor/actuator placement.…”

Disturbances acting on flexible structures at spatially varying locations instead of fixed points may lead to deteriorated vibration control performance. To tackle this problem, this article presents an optimal sensor/actuator placement method, in which the closed-loop spatial [Formula: see text] norm is employed as the optimization criterion. In addition, a new way to calculate the spatial [Formula: see text] norm is proposed, which is independent of the modal orthogonality assumption in previous research. An optimization framework is established to optimize sensor/actuator placement by minimizing the closed-loop spatial [Formula: see text] norm using the genetic algorithm. Comprehensive numerical simulations are implemented on a fixed-fixed plate to validate the proposed method. Results show that magnitude of vibrations is reduced and decays faster after the optimization, which indicates that the proposed method markedly improves control performance when spatially varying disturbances exist.
