Said to the linear actuators, believes everyone not unfamiliar, because all around us, a lot of mechanical devices have the use of these linear actuator, as the demand of the different mechanical equipment use, these types of linear actuators are also growing, closed-loop linear actuator is our one of the most common, the small make up a closed-loop linear actuator is to tell you about the structure and the use of the advantage of, hope you can understand and use these closed-loop linear actuators. Open loop control system has the advantage of simple structure, economical. The defect is unable to eliminate the interference caused by the error. Compared with open loop control system, closed loop control with a series of advantages. In a feedback control system, for whatever reason, external disturbance or within the system changes, as long as the controlled quantity deviating from the specified value, can produce the corresponding control action to eliminate the deviation. Therefore, it has the ability to suppress interference is not sensitive to element characteristic changes, and can improve the response of the system. But the introduction of the feedback loop to increase the complexity of the system, and the improper selection and gain can cause instability of the system. In order to improve the control accuracy, when the disturbance variables can be measured, is often adopted according to the disturbance of the control at the same time, the feedforward control supplement feedback control and compound control system. And closed loop control system based on feedback principle of automatic control system. The so-called feedback principle, is based on the system output change information to control, through comparing the system behavior and expected behavior, the deviation between the and eliminate bias to achieve the expected performance of the system. Hope all of us at the time of use linear actuators, able to fully understand the structure of it, so use rise more convenient, at the same time, we also want to according to the needs of their production, select the appropriate linear actuators, in the process of the linear actuators to run, also want to pay attention to its running state, only in this way, can the biggest role in extending the linear actuator for our equipment operation and reliable equipment. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
