“…Hence, a variety of open-loop and closed-loop control strategies have been proposed to reduce motion-induced vibration. Input shaping is one of the most popular and practical open-loop feedforward control strategies in reducing vibrations of flexible components of spacecraft [10,11] , flexible manipulators [12,13] . An input shaping approach modifies the reference signal for the system, such that it will avoid introducing unwanted oscillations in the system [14] .…”

Nowadays, new concepts of active compliant structures employing smart materials are receiving increasing attention to design high-precision lightweight mechanisms, however, bring a new challenge to deformation control system design, especially considering the coupling with rigid motion control. An important issue for such a rigid/compliant system is to realize a fast, smooth hybrid motion/deformation control effect with minimized structural vibration in a given time interval. A rotating compliant manipulator actuated by an electric motor and distributed piezocomposite patches is utilized for investigation towards motion/deformation control. Open-loop simulations imply that structural vibration can be excited by both rigid motion control and deformation control. A finite-time terminal control design approach is developed using a new quadratic objective function which is formulated by (generalized) acceleration, instead of the state (composed of generalized displacement and velocity) and input of the system in regular formulation, to improve the terminal control effect without sharp change in the input profiles. The time-varying control law is obtained by solving a set of DREs. Pure and hybrid motion/deformation control with conventional and new objective functions are presented and discussed. The results imply that more smooth dynamic responses for hybrid motion/deformation control performance with minimized residual vibration can be obtained by using the new acceleration-based objective function, while the state and input at the terminal point are the approximate analytical steady-state. The new objective function also has unique merit in that the associated weighting matrix can be intuitively chosen with better robustness. Hybrid objective functions with a combination of the conventional and new acceleration-based terms can be employed to obtain favorable comprehensive control performance and bring a wider margin for the designers.

“…A variety of control techniques including the optimal Positive Position Feedback (PPF) control, simple adaptive control, input shaping combining classical control, LQR control, and sliding mode control have been used in the gyroelastic body by the researchers (E et al, 2020; Hu et al, 2013a; Jia and Shan, 2018a, 2018b, 2019). However, uncertainties due to change in system parameters with time and environmental factors are inevitable in the actual system (Fanson, 1987; Kumar, 2013; Youn et al, 2000), and none of these methods is suitable for the system with parametric uncertainties.…”

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.

“…Passive vibration isolation method has better high frequency vibration isolation capability, while active vibration isolation mainly has good suppression effect on low frequency vibration, including many methods, [9][10][11][12][13] such as PID control, adaptive control, component synthesis method, etc. Active-passive integrated vibration isolation method combines the advantages of the two and expands the vibration isolation bandwidth.…”

This paper puts forward realizing the synchronous control of spacecraft attitude and micro-vibration by taking advantage of magnetic suspension rotor deflection of magnetically suspended control and sensitive gyro. A disturbance-observer is designed to estimate the complex micro vibration which is hard to measure, and an adaptive robust sliding mode controller is designed as an integrated controller and its stability is proven by Lyapunov stability criterion. The band-pass filters are introduced to separate low frequency and high frequency control signals and takes them as input commands of gyro frame and magnetic suspension rotor, respectively. The semi-physical simulation results testify that the proposed method has good vibration suppression effect as well as improves the attitude convergence rate.
