“…Motor drive is characterized by simple structure, cheap and convenient control, so motor is adopted as driving source. 29 , 30 Because the clutch driving mechanism is designed to convert the rotational motion of the DC motor to the linear motion of the actuator, the mode of worm gear and worm drive is employed in this paper. The transmission system of the actuator is composed of one-stage worm gear pair and two-stage planetary gear pair.…”

Tractors installed automated manual transmission can avoid discomfort for the drivers because of excessive limbs intervention as well as improve shift quality. Automatic clutch control is critical for the performance of the automated manual transmissions. For a good operation, precise and fast control of clutch position is mandatory. In order to meet these requirements, an enhanced strategy focused on the clutch is presented adopting a simple tracking control method based on the detailed models in this study. Clutch models including DC motor model and mechanical actuator model are established and transformed to a controllable model. On the basis of the control model, a clutch position tracking control scheme is proposed composed of motor control circuit and motor angle tracking controller designed according to the backstepping method. Simulations are carried out in comparation with the internal model control method, and the results demonstrate the effectiveness of the presented control scheme by superior rapidity and accuracy of the controller response for the clutch position tracking system.

“…The compensation effectiveness of the UPQC depends on its ability to follow with a minimum error and time delay the reference signals [32]. The conventional techniques reported in literature produce poor results under distorted and/or unbalanced input/utility voltages, and they involve many calculations [20]. The proposed control scheme is a simple method to achieve effective compensation for source current harmonics, reactive power compensation and voltage harmonic mitigation under distorted and/or unbalanced input/utility voltages.…”

“…Errors for each phase are discretized by the zero order hold blocks; the error rate is derivative of the error and it is obtained by the use of unit delay block; the saturation block imposes upper and lower bounds on a signal [44]. When the input signal is within the range specified by the lower and upper limit parameters, the input signal passes through unchanged otherwise the input signal is outside these bounds in this case the signal is clipped to the upper or lower bound [20]. The outputs of these fuzzy logic controllers are used in generation of pulses switching signals of the seven-level inverter.…”

“…The conventional control scheme to generate pulses, based on hysteresis technique control, presents several drawbacks such us uneven switching frequency that causes acoustic noise and difficulty in designing input filters in case of SAPF. To improve the APF performance, the tendency has been to use intelligent control techniques [19,20] particularly fuzzy logic [21]. The use of these techniques in power electronics applications has generated considerable interest [22].…”

This paper presents novel Unified Power Quality Conditioner (UPQC) system based on seven-level Neutral Point Clamped (NPC) inverter using combined PD-SPWM and fuzzy control scheme. The proposed UPQC is adopted to mitigate source current harmonics and compensate all voltage disturbances simultaneously. It is designed by the combination of series and shunt Active Filters (AFs) connected by a common DC link capacitor. The DC voltage at common DC bus is maintained constant using proportional integral voltage controller. The Synchronous Reference Frame (SRF) method is used to get the shunt APF reference signals and the power reactive theory (P-Q theory) for the series APF. Conventional control schemes require complex calculations, the use of intelligent systems help to reduce the control system size and the operation complexity. The shunt and series Active Power Filter (APF) reference signals derived from the control algorithm are injected in Fuzzy intelligent controllers to generate switching signals. The functionality of proposed UPQC system and its control system is evaluated using Matlab-Simulink software and SimPowerSystem Toolbox under various operation conditions in cases of most common power quality problems such as voltage sag, voltage swell, current harmonic compensation of nonlinear loads and unbalanced load. The simulation results show UPQC performances to improve the power quality in steady and transient conditions operation at the point of common coupling on power distribution under unbalanced and distorted voltage conditions.

“…Some works have also considered the time-varying and parameter-varying characteristics of the feed system. [17][18][19] In particular, significant progress has been made in dealing with parameter perturbations and external disturbances of motor drive systems based on fuzzy methods, [20][21][22][23] and in recent years, more scholars have further combined this method with neural networks, and the control improvement effect is remarkable. 24,25 Furthermore, the influence of nonlinear factors of the feed system, such as clearance 26 and input saturation, 27 on the motion accuracy has also been analyzed and improved.…”

The use of mechatronic integrated equipment, such as servo feed drive systems, has become increasingly important in high-end manufacturing, aerospace, and semiconductor industries. However, while advancements in modeling and analysis have improved deterministic feed systems, there is a lack of research into uncertain motion accuracy due to random factors in actual working conditions. This paper aims to address this issue by analyzing the uncertainty of motion accuracy in single-axis feed drive systems. Random factors already impact both positioning accuracy and repeatability, while dynamic errors are reflected in the mean and variance of following errors. The study also considers the impact of disturbance uncertainty, parameter uncertainty, and model uncertainty on motion accuracy. To investigate the impact of these sources of uncertainty on a six-degree-of-freedom linear motor feed system, a simulation example using the Monte Carlo simulation algorithm was utilized. The analysis revealed that uncertainty indeed has an impact on motion accuracy. This research will help identify and improve random errors in servo feed systems, ultimately leading to the development of strategies for reducing motion accuracy uncertainty and enhancing the accuracy and reliability of feed systems in high-end manufacturing, aerospace, and semiconductor industries.
