“…According to (31), the derivative of the included angleθ to λ is (32), and its norm becomes smaller and smaller with the increase of λ, that is, the larger the value of parameter λ, the weaker its ability to adjust the direction ofδ. For example, if λ changes from 0 toδ τ , θ changes from 90 to 45 degrees, λ continues to change fromδ τ to 10δ τ , then θ changes from 45 to 5.71 degrees, finally λ changes from 10δ τ to infinity, and θ changes only from 5.71 to zero degree.…”

The single-gimbal control moment gyros (SGCMGs) steering law has been a standing topic in the field of spacecraft attitude control for several decades. A practical steering law should meet the following requirements simultaneously: powerful singularity avoidance ability, high precision torque output ability and fast singularity escape ability. Moreover, the angular velocity commands generated by the steering law should not jitter sharply. In this paper, a vector control-based singularity avoidance and escape steering law for SGCMGs is proposed to satisfy these goals. In addition, a system angular momentum state evaluation function for command torque is defined for the first time, which can be used to effectively evaluate the remaining angular momentum resources for the command torque. We demonstrate the effectiveness and superiority of the proposed steering law with detailed comparisons to existing efforts.

“…In Hu's studies, the angular momentum is discretely distributed in the structure rather than continuously [6,7]. According to the model in [11], Guo et al proposed a modal force compensator method [14] and a null-motion based method [15] to suppress vibration. Different from the idea of designing the control law and the steering law of actuators together [10][11][12][13][14][15], Hu et al [16,17] proposed two control law design methods for attitude control and vibration suppression.…”

“…For solving vibration problems above, active vibration suppression methods are more effective in practical engineering (Fanson, 1987;Williams, et al, 2019;Zhang and Li, 2020). Angular momentum exchange devices, which can provide sufficient, continuous, and precise control torques under the condition of occupying only a small internal space, are a kind of control actuators widely used for active vibration suppression (Guo et al, 2018;Gupta et al, 2011;Hu et al, 2013a, Wang et al, 2017. D'Eleuterio (1991) studied the controllability and observability of gyroelastic body.…”

Gyroelastic solar panel is a kind of flexible solar panel structure with variable-speed control moment gyroscopes distributed inside. The torque generated by these variable-speed control moment gyroscopes can be used for active vibration suppression. This paper addresses the vibration suppression problem of gyroelastic solar panel in the presence of parametric uncertainties and un-modeled dynamic uncertainties. A novel μ-synthesis method based on analytical multiple-input multiple-output weights design is proposed, which relates 2-norm of the vector of regulated outputs, closed-loop modal damping, and relative control ability of actuators to each mode to the weights. Based on the idea of collocated control, the full order state-space model of the constrained gyroelastic plate with angle gyros as measuring devices is derived. After model reduction, modeling of un-modeled dynamic, and designing the multiple-input multiple-output weights, μ-controller is solved by the DK-iteration method. Furthermore, a comparative study of the μ-controller designed by the proposed procedure and the Positive Position Feedback (PPF) controller designed by the non-smooth H∞ synthesis method is also presented. The control methods are compared for their vibration attenuation, energy utilization, robustness performance characteristics, and robustness stability characteristics. Results for both time domain and frequency domain simulations are presented. Simulation results show that the designed μ-controller has better vibration attenuation effect and robustness performance characteristics than the PPF controller, and can achieve a better robust vibration suppression of the constrained gyroelastic solar panel in presence of parametric and un-modeled dynamic uncertainties.
