“…In both pieces of literature, sliding film control is used, and it is seen that the sliding film control algorithm occupies a superior position in terms of high accuracy and strong stability in working conditions, so this paper uses a non-singular fast terminal sliding film surface design controller. The use of position synchronization techniques in linear servo systems is also more widespread [9][10][11]. In the literature [12], a finite-time adaptive neural network (NN) position-tracking control method is proposed, and the simulation results show that the motor tracking performance under the control of this method is better, but the paper does not simulate the anti-disturbance property.…”

In order to improve the position high-precision synchronization performance of multi-motor synchronous control, a multi-motor position synchronization control method based on non-singular fast terminal sliding mode control (NFTSMC) combined with an improved deviation coupling control structure (Improved Deviation Coupling Control(IDCC), NFTSMC+IDCC). Firstly, this paper designs a sliding mode controller using a non-singular fast terminal sliding mode surface with a Permanent Magnet Synchronous Motor (PMSM) as the control object. Secondly, the deviation coupling is improved to enhance the coupling between multiple motors and achieve position synchronization. Finally, the simulation results show that the total error of multi-motor position synchronization under NFTSMC control is 0.553r in the simulation of multi-motor synchronization control under the same working conditions, which is 2.873r and 1.772r less than that of SMC and FTSMC in terms of speed error, and the anti-disturbance performance is 83.68% and 76.22% higher than that of both of them, respectively. In the subsequent simulation of the improved multi-motor position synchronization structure, the total error of the multi-motor position is in the range of 0.56r-0.58r at three speeds, which is much smaller than the synchronization error under the Ring Coupling Control (RCC) structure and Deviation Coupling Control (DCC) structure, showing a better The synchronization error is much smaller than that of the RCC structure and DCC structure, which shows better position synchronization performance. Therefore, the multi-motor position synchronization control method proposed in this paper has a good position synchronization effect and achieves the control effect of small displacement error and fast convergence of the multi-motor position synchronization control system after being disturbed, the control performance is significantly improved.

“…Liu Jia [4] proposed a high synamic synergetic control method based on state space model of the DC-Servo system. A position synchronized control strategy to deal with the synchronous error caused by the external disturbance in dual linear motors servo system was introduced in [5]. An optimal design method was proposed to determine the PID coefficients for control discrete-time SISO LTI systems in order to improve the transient tracking performance [6].The jumping problem of elastic stiffness coefficient caused by different working condition of the rolling mill hydraulic servo system was discussed in [7].…”

in this paper, a very low cost two-axis position servo system is developed. This system is controlled by DSP. We study the stability of the position servo control system. We use the PI control algorithm in our application. We achieved twice switching frequency by using PWM signals to share the switching dissipation ePWM module of the DSP. A numerical consideration is given. The simulation results demonstrate the stability of the proposed method.
