“…This description of parallel linear slider (2) is called as 'decoupling model.' The effectiveness of this description was shown in the previous researches [1], [3]. Using this decoupling model, we design the controller which produce the driving force and torque.…”

“…If we assume that reference signals and measurement delay do not exist and mechanical characteristics of each mover are completely same, then the responses of each mover are synchronized, then we can attain an enough control performance of table position. But, it have already K. Sato honda@life.kyutech.ac.jp been pointed out that we apply P-PI control method for each mover then we can not select large speed loop gain [1]. It was also shown that if we select speed loop gain as large, then each motion of mover does not synchronize.…”

“…It was also shown that if we select speed loop gain as large, then each motion of mover does not synchronize. To solve this problem, a decoupling model for a parallel linear slider was proposed [1]. In this method, the motion of parallel linear slider is divided as linear motion and rotary motion of centre of mass of table.…”

This paper considers an adaptive H ∞ control method for decoupling model of parallel linear sliders. The decoupling model that divide the dynamic model of the parallel linear sliders into translatory movement and rotary movement is proposed. Based on this model, an adaptive H ∞ control strategy is also given. The proposed method ensures that the unknown parameters are estimated, besides, an approximated errors of external disturbances are attenuated by means of H ∞ control performance. In spite of considering the nonlinear adaptive H ∞ control problems, the compensator can design without solving the Hamilton-Jacobi-Isaacs equation. Simulation results are given to illustrate the effectiveness of our proposed method.

At present, many industrial carrier devices utilize linear motor sliders. However, a heavier load requires a linear motor (which is an example of a direct drive device) to get higher power, compared with a rotary motor with a ball screw slider (which is an example of an indirect drive device). In order to obtain higher power at a lower cost, a linear slider with multiple motors can be utilized, for example, a gantry type linear motor slider. Moving the gantry type slider requires two linear motors that are set up in parallel to enable synchronization control. Some conventional synchronization control methods have been proposed for the parallel twin linear slider; however, a large-scaled gantry type linear motor slider has two unique problems: mechanical distortion caused by the limitations of installation environment and coupling caused by joints with low stiffness. This paper proposes a control model to solve these problems, and an identification method of each parameter. Furthermore, the effectiveness of the control model is verified by comparison with simulation results and experimental results. C⃝ 2018 Wiley Periodicals, Inc.
