Fuze High Accruacy Dynamic Open-Loop Control Technology Based On Simultaneous Power And Information Transfer

In order to adapt to the three-dimensional threats existing in modern warfare and improve the information response and fire response capability of tanks,it is necessary to use information-based multifunctional tank gun ammunition to replace the traditional single-damage mode ammunition.This type of multi-functional ammunition has changed the defect that traditional ammunition has only a single function of damage and it is difficult to combat hostile targets under various complex environmental conditions.In order to achieve multiple damage effects of multi-functional munitions,the fuses used for such munitions must also have four capabilities that can be set,detectable,processable and controllable.This type of fuze serves as a dynamic open-loop control system,which improves the accuracy and reliability of dynamic open-loop control to achieve the best approach to damage control.The theory of dynamic open-loop control in the process of fuze flight is focused on,andthe factors affecting the accuracy and reliability of the dynamic open-loop control system are analyzed.It proposes the introduction of new energy and information sources and enhancements.The current information

synchronous transmission is designed;Dynamic open-loop control of energy flow and information flow in the system and proposes a control reliability/accuracy optimization method based on energy flow and information flow.The optimization method is divided into two parts:the impact of simultaneous transmission of energy and information on the system optimization and energy flow In order to evaluate the influence of the energy and information synchronization transmission system based on the transmission loop on reliability and accuracy,a relative entropy evaluation method of dynamic open-loop control effect is proposed,and the dynamics based on simultaneous transmission of energy and information are completed.Open-loop control system basic theoretical framework.In view of the problem of strict power constraints in transmission systems based on transmission loops,power allocation strategies,system models,and transmission timings for energy and information synchronization transmission under power constraints are studied.The work goal of the system is to achieve the shortest total transmission time on the premise of providing sufficient energy(guaranteeing reliability)for the fuze so as to improve the real-time performance of the information(increasing accuracy).The power distribution strategies of energy and information transmission processes at the transmitting end and receiving end under power constraints are analyzed.The boundary between the energy transmission efficiency and the information transmission rate is calculated based on the ideal receiver filter;two types of synchronization are established:low communication channel and communication channel.The transmission model,the performance comparison of the two shows that the low-communication channel transmission model is superior to the transmission model with communication channel;the transmission system based on hybrid power allocation is designed,and the transmission timing is optimized by minimizing the transmission time length as the optimization goal.The optimal transmission timing and the shortest transmission duration are analyzed.The influence of the non-ideal receiver filter on the transmission system is analyzed.The results show that the non-ideal receiver filter affects the system bandwidth.Finally,the energy and information synchronization transmission system model under power constraint is established.For the purpose of improving the control reliability,the mutual crosstalk between the launching energy and the settling energy and its restraining means are studied.For the crosstalk failure mechanism problem,an inter-system energy flow crosstalk failure model based on non-polymeric Markov chain is established.According to the failure model,the influence of energy flow crosstalk on each subsystem is analyzed;the crosstalk suppression effect of energy flow is determined according to the energy flow crosstalk effect and the crosstalk suppression function is designed.The positive and negative voltages are designed by different parameter values.This type of crosstalk suppression system simulates the crosstalk suppression effect and the reliability of the crosstalk suppression system.The analysis results show that the suppression effect of the positive voltage and negative voltage crosstalk suppression system is close,and the positive voltage crosstalk suppression system has certain advantages in terms of reliability,so the positive voltage is selected.The crosstalk suppression system design scheme serves as the final design of the crosstalk suppression system.The influence of the dynamic open-loop control error on the accuracy and the control error correction algorithm are studied.The basic theories of error correction of open-loop control are proposed.The theory divides the control error into two parts:the reference error and the model error.For the reference error,it is To ensure the long-term stability of the reference in the case of temperature changes,a two-step calibration scheme for controlling the reference was designed.Step one,a control reference based on bidirectional pseudo-timestamp synchronization and a timing starting point correction algorithm,step two,temperature-based control Reference self-correcting algorithm;Based on the model error,a model error correction algorithm based on dynamic fixed energy test results was designed.The algorithm corrects the model error by sampling the conditions of the test results.A dynamic open-loop control system based on the simultaneous transmission of energy and
