“…Therefore, v 0|k+1 = v(k + 1) ≈ ω e (k) is assumed. Meanwhile, similar to (15), by substituting model ( 19) and ( 22) into (4), the CCS-MPCC with one-step delayed MAESO compensation is derived as follows:…”

“…High current loop bandwidth improves overall performance, including speed loop settling time, which is helpful for those applications that require fast response. Examples of systems requiring high bandwidth because they need the motor to reach the specified position in the fastest time, are, for instance: rapid sorting by manipulators, high-speed soldering of wire bonding machines [14], high-speed placement for chip mounters [15], and many others. Besides, high current loop bandwidth allows the outer loop gain to be reduced, while still maintaining the same performance without causing noise amplification.…”

Model predictive current controller is a popular and effective technique to provide fast dynamic response in the field of motor control. However, conventional predictive controllers are susceptible to deteriorating control performance when model mismatch exists, such as changes in motor parameters due to the temperature variations. Therefore, this article proposes a precise model-aid extended state observer (MAESO) compensation-based real-time model predictive current controller with enhanced parameter robustness performance and high bandwidth. The predictive controller is converted into the form of multiparameter quadratic programming for online solution using numerical computational method and the constraints are linearized. In addition, the disturbances estimated by MAESO are fed back to the controller in the form of parameters for cycle-by-cycle compensation without extra controller design. Comparative simulations and experiments under different operating conditions are carried out to verify the effectiveness and superiority of the proposed method. Index Terms-Extended state observer (ESO), model predictive control, permanent magnet synchronous motor (PMSM) drive, quadratic programming. I. INTRODUCTION F OR many years, permanent magnet synchronous motors (PMSM) have received continuous attention [1], [2], [3], [4] due to their high torque density, efficiency, and simple structure. They are widely used in almost all industrial fields, such as manipulator joints [5], robotics or servo systems [6], moreover they are common choice in electric vehicles [7], [8].

“…Hu et al [18] proposed an optimal efficient motion control method based on the S-shaped velocity planning method. Firstly, according to the constraints of motor parameters and boundary speed, the feasible region and the time series on the acceleration or deceleration section of the S-shaped speed curve are determined; Then, based on the displacement constraints of the starting point and the end point, the time distribution of the S-shaped velocity curve is updated with the goal of optimal efficiency; Finally, according to the calculated time series, the point-to-point real-time motion control is realized based on the S-shape velocity planning algorithm.…”

With the continuous development of the new generation of semiconductor devices and modules, the size of high-end chips has also been further reduced. With the purpose of adapt to the rapid development of high-end chips, the chip mounting technology and equipment have also entered a rapid iterative development stage. Nowadays, the chip mounter is developing towards the direction of high intelligence, high precision, high efficiency, green and automatic. High precision patch equipment has been the focus of research at home and abroad. This paper summarizes the current situation of the demand for high-precision mounting technology of optical module laser in the 5G/6G field, introduces the main performance index requirements of high-precision mounting machine equipment, and systematically expounds the application status, advantages and disadvantages of high-precision mounting machine from three aspects of visual detection technology, mounting path optimization, and motion control system. The research shows that how to improve the speed and precision of mounting is still the bottleneck of the industry. Therefore, the research on the key technology of high precision and high-speed mounting has become an important competitive focus in the field of chip mounter equipment.
