In this paper, with the research task of a certain type of rocket launch platform, carrying out in-depth research from the overall system design,control strategy,hardware circuit and software programming and so on. In the entire system design, the master computer and the slave computer are combined and used, and the first one is used for human-computer interactive, information processing and commanding and dispatching, and the other one is used for position collecting,algorithm processing and the control of motor.In the position servo system, choosing the PMSM as the actuator, Based on the high performance indicators of the rockets, and in the actual launch of the rocket considering the characteristics such as time-varying parametersã€burning gas flow and load torque all bring bad impact to the control of rocket launch. The traditional control strategy can not meet the operational requirements. In this paper, on the basis of the terminal sliding mode control, introducing of RBF neural network adaptive control. The simulation results verify the correctness and validity of the composite strategy. In the design of the system’s hardware circuit, the design scheme of the master computer is based on the ARM7-based processor. Emplacement computer, the slave computer, ignition and display screen realize data communication with the master computer through the serial ports,such as RS422or RS232. At the same time in order to ensure safe operation, software limit and hardware limit circuit are designed. The design scheme of the salve computer is based on the DSP-based processor. Drive the servo motor to carry the gun body track and aim through the D/A conversion circuit, amplifying circuit, RDC module, DDS excitation module. Software is designed in two parts, one part is the master computer software design, and is designed in the AD1.2compilation environment; another part is the slave computer software design, and is designed in the CCS3.3compilation environment.Finally, verify the correctness and reliability of the composite control strategy, the hardware circuit and software programming through the rocket launchers prototype experiment platform. |
