【摘要】 本文共两篇。 第一篇介绍用于某型通用电子干扰设备的数字伺服系统的研究。该伺服系统采用交流驱动方案、轴角检测系统和智能PID控制方案实现了系统的全闭环控制。本研究设计了基于PC／104总线的计算机控制系统。文中对智能PID控制算法进行了研究，并作了实际系统调试，结果表明该系统的性能达到指标要求。最后，本文对机载伺服系统进行了初步设计。 第二篇介绍用于某型远程火箭弹角稳系统的数字跟踪滤波器的研制。系统要求滤波器既能滤除各种噪声，又不产生相位滞后。为此研究了非线性微分校正，能产生相位超前，用于补偿滤波器的相位滞后且不增加高频增益，后又提出基于相位与幅值补偿的滤波器的设计。本文用MATLAB作了仿真研究，并在单片机系统中进行工程实践。最后，本文对滤波器的进一步研究提出了建议。更多还原

【Abstract】 The paper is composed of two parts.In the first part, a style of digital Servo-System is developed, which will be applied to the electronic interference device. The closed-loop control is realized by applying AC driving scheme, Resolver-to-Digital converter system and intelligent PID control strategy. The controller design basing on PC/104 bus is introduced in the paper. Experiment results show that good performance can be achieved when intelligent PID is applied. Finally, the design of the Servo-System for the jet is introduced.In the second part, a style of digital tracking filter is introduced, which is used in the phase steady system of a style of long-range rocket. The filter is required to filter some noises and keep against lag of system phase. A kind of nonlinear differential filter for the phase compensating, and the other filter basing on the phase and amplitude compensating are introduced in the paper. The filter designed is simulated by MATLAB and debugged in SCM. Finally, some beneficial suggestions are put forward for the far research.更多还原
