With the continuous improvement of the level of intelligence in the construction machinery industry, as one of the core technologies in the hydraulic lifting and rotating system, the lifting transmission control system has become a key factor in determining the performance of the elevator. As a hydraulic lifting machine with high protection level and powerful functions, the mechanical transmission controller has been recognized by the market. This study is based on the design of lifting machinery transmission control of hydraulic lifting and rotating system and studies the lifting mechanism transmission system in the hydraulic lifting and rotating system required for engineering operation. According to the functional characteristics of the transmission controller of the lifting mechanism, the control system scheme is designed. On this basis, the system design of the lift machinery transmission control and, according to this design, the functions of driving speed control and transmission mode switching are studied. Starting from the movement mechanism of hydraulic continuous lifting technology, this research carried out the principle design of mechanical transmission control, related calculations, selection of hydraulic components, corresponding simulations, structural design of mechanical transmission, and tests of hydraulic power systems. Finally, the control system was verified through simulation experiments, and technical difficulties such as the liquid supply mode of the large-flow system, the selection of standby working conditions, and the reliability and safety design were solved. It can be seen from the simulation results that, as the displacement ratio increases, the system efficiency increases, reaching more than 70%. When the valve opening reaches 20° when the valve port is closed, the efficiency of the power control valve reaches 95%. It can be seen that the control system established in this study has more advantages in power and economy. The transmission control system of hoisting machinery designed in this study can give greater play to its transmission efficiency and significantly reduce the working time and intensity of the operator.

“…Slow convergence and even divergence will occur if the coupling in control channels is not properly dealt with (Xie et al, 2020a). Some control algorithms considering the crosscoupling effect (Kasbekar et al, 2015;Li et al, 2016;Shi et al, 2019;Xie et al, 2020aXie et al, , 2020b have been employed to remove the risk of divergence. However, the computational complexity will increase exponentially with the number of channels (Shi et al, 2019) and pose sharp challenges to a digital controller.…”

It is necessary to cut off all vibration transmission paths for an active vibration isolation system. A greater suppression of local responses will result in a better overall attenuation. In order to realize impediment at possible transmission paths, a new scenario of multi-axis transmission control is proposed, in which the active/passive isolator attenuates vibration transmission at multi-degrees of freedom by vertical and horizontal actuators mounted orthogonally on the intermediate inertial mass. This scenario is able to weaken the cross-coupling of control action between isolators by the passive parts. In order to investigate the characteristics of multi-axis transmission control, the dynamic model of a partitioned isolation system with one active/passive isolator is established and the involved transmission control is analyzed. The numerical results show that the foundation vibration can be attenuated along with the decrease of vibrations of the intermediate inertial mass. It is further revealed by experimental results that the multi-axis transmission control at the intermediate inertial mass is necessary to achieve sufficient vibration attenuation in the foundation, whereas the control in a single axis is ineffective. These verified results imply that the active/passive isolation with local transmission path control makes it possible to apply decentralized control in a large active vibration isolation system.

“…Yang et al (2017a) proposed a multi-model negative acceleration feedback control method to suppress the vibrations of multi-degree-of-freedom systems using a single active mass damper consisting of an AC servo motor. Xie et al (2020) installed the electromagnetic inertial actuators on the four bases of the submarine cabin, and put forward the FxLMS (Filtered-x Least-Mean-Square)-based multi-channel global control method to suppress tonal vibration transmission. However, the additional mass of electromagnetic inertial actuators was also large, and there was a risk of electromagnetic interference with other electronic equipment, which will affect the safety and reliability of the equipment.…”

To tackle the active control problem of the heavy platform-struts structure, this paper designs a kind of hydraulic servo actuator that can withstand large static load and generate high-precision, small-amplitude dynamic forces as well, and develops a multi-channel cross-coupling suppression control algorithm that can consider the strong coupling effect in structure. Subsequently, combining the designed actuators with the control algorithm, this paper puts forward an active heavy platform-struts structure vibration control method. By embedding the designed actuators into the support struts, a platform-struts structure experimental system is constructed to assess the vibration suppression effect of the proposed method. Excited by the amplitude-varying disturbing force, four different kinds of experiments are conducted. The experimental results show that the distributed multi-channel adaptive active control method without considering the coupling effect will lead to the instability, and the vibration attenuation of the proposed method in this paper exceeds 90%. The proposed method therefore has an important potential in addressing the problem of vibration suppression in the practical engineering. In addition, it has strong convergence and robustness.
