“…12 Based on linear quadratic regulator (LQR) theory, Jin et al conducted simulation analysis on vibration control of flexible cable and verified the effectiveness of active LQR control. 13 Krarup et al adopted the pole distribution control method to design an active controller, the simulation results indicated that this method can suppress the low frequency vibration of flexible cable to a certain extent. 14 Li et al adopted linear quadratic Gaussian controller (LQG) with self-powered capability to obtain the optimal active control force and demonstrated its effectiveness through simulation.…”

Effective vibration control of flexible cables is increasingly demanded for space flexible structure. For the low frequency dynamics of flexible cables, a novel vibration control strategy based on sliding mode control is proposed in this paper. First, the complex dynamical behavior of flexible cables is modeled using D’Alembert’s principle. Second, an improved dual power reaching law is put forward to better address the chattering problem of the sliding mode controller. Then, an extended state observer (ESO) with the radial basis function (RBF) neural network is designed to compensate for internal uncertainties and external disturbances as well as further improve the control accuracy. Lyapunov function is employed to analyze the stability of the system. Finally, considering the large number of parameters of the proposed controller, an improved particle swarm optimization (PSO) algorithm is designed to automatically adjust these parameters. The effectiveness of the proposed method is demonstrated by simulation results.

“…The references [2,3] optimized the structure of the cable-driven parallel robot (CDPR) with the maximum stiffness as the optimal goal to enhance the ability to resist vibration, but the manipulators in the papers are move in low-speed, which is not suitable for the high-speed manipulator. The references [4,5] restrain the vibration via the auxiliary device (such as reaction wheels or damping actors) of the CDPR, however the auxiliary device adds complexity of the manipulator and the CDPR is the small-span manipulator.…”

Cable-driven camera robot has the characteristics of high load/mass ratio, large working space, fast response speed and strong environmental adaptability, which has a wide application prospect and important development value. However, the high-speed movement of the camera robot has a great impact on its performance, and an optimal design method that meets its actual characteristics is needed to improve its overall performance. In view of the shortcomings of the standard genetic algorithm, such as premature convergence and insufficient global optimization searching ability, an improved genetic algorithm is proposed. Compared with the optimization results of the standard genetic algorithm, The improved genetic algorithm converges to the global optimal solution and the impulse decreases obviously, it shows that the improved genetic algorithm is more effective and practical, and reduces the impact of cable tension, thus obtaining better camera robot design parameters.
