为了研究冲压式气动舵机柔性气囊的行程与控制信号之间的规律,利用FPGA构建了一个可编程片上系统(SOPC)实现同时对多个伺服机构的控制;详细论述Nios II嵌入式系统的PWM从外设设计方法,并将PWM应用在冲压式舵机测试与控制系统;实验结果表明,该舵机控制器不仅控制参数设定方便、控制精度高且稳定性好,而且增加了系统使用的灵活性及可靠性.%To study the law between the trip of ram-air balloon actuator and control signals, a kind of multiple actuator control system by using a Programmable System on Chip (SOPC). This paper introduces the method of designing a PWM controller based on Nios Ⅱ embedded system in detail, the PWM controller will be used in missile actuator test. Experimental results show that the controller can receive communication data, and control each missile rudder independently and the operation is stable, and flexibility and reliability of the system.
