介绍了某型无人机的数字式舵机控制器的设计。由于原使用的模拟式舵机控制器的控制参数不易调整,且用于调整参数的电位器极易出现故障,设计了使用TMS320F2812作为CPU的数字式舵机控制器。本控制器使用DSP芯片对多路舵机实现了伺服控制,不但体积大大缩小,而且控制性能更加优良,并实现了系统的各主要控制参数的不拆机修改,增加了控制器的灵活性以及通用性。 The design of a digital servo controller for a UAV is introduced. As the original control parameters of the analog servo controller is not easy to adjust, and the potentiometer used to adjust the parameters are prone to failure, designed using the TMS320F2812 as a digital servo controller. The controller uses the DSP chip to realize the servo control for the multi-servo, not only the volume is greatly reduced, but also the control performance is more excellent, and the main control parameters of the system are not disassembled to be modified, increasing the flexibility of the controller and Versatility.
