Abstract


This thesis is a military water sound measuring device developed for the background , in-depth research and development of one of the the rotary fixed depth control system . In view of the charged objects with ultra-low -speed characteristics of low noise performance and high-precision positioning requirements , proposed to build the control of a distributed control system under the premise , rotary and fixed depth control subsystem digital PWM brushless DC torque motor control program. Current, speed and position of the tricyclic compound regulating control structure , current loop PID control algorithm, and the speed and position loop using Intelligent Fuzzy-PID control algorithm . Same time , based on the the ATmega8 microcontroller development of motor drive mainly used brushless DC torque motor drive and current closed loop regulation , the AT90S8515 microcontroller as the core communication controller is mainly completed speed , the location of the closed-loop regulation and the data exchange between the host computer . Finally, system modeling and simulation results show that the fuzzy - PID control algorithm used in this paper to fully meet the positioning and speed control system in response to the requirements of the regulation of the speed and position loop , and verify the feasibility of the algorithm .
