A Dynamical Switching Algorithm of Repetitive Frequency Electromagnetic Launch

With the development of electromagnetic launch (EML) technology, the demand for engineering and practicality of electromagnetic energy device has become increasingly urgent. The working mode of repetitive frequency launch increased higher technical requirements for the primary power supply, pulsed power supply, loading system, and close coordination and strict time sequence control among various systems. Based on the requirements of repetitive frequency operation, the control architecture based on the primary power supply cascade controller, pulsed power supply time sequence trigger, and loading system control machine is build, and a control network is constructed using optical fiber composite communication. By designing the logical relationship between control signals and feedback states among each controller, a control strategy following the repetitive launch process is established. The close cooperation and effective control of the various systems are achieved, and the repetitive frequency launch experimental task is completed. The experimental results demonstrate that under the communication method and control strategy, the design indicators of repetitive frequency launch were met and the control strategy is effective.
