Designs On The Stabilization Loop Of Gyro Platform

The inertial navigation system plays an important role in the development of navigation and aviation. The stabilized platform is one of the most important part in the inertial navigation system, which determines the system's precision The solution of conventional platform stabilization loop is constructed by classical PID law and analogue electronic system, which is not so satisfied in precision, respond speed and disturbance rejection. And the analogue electronic system has the shortcoming of big bulk and high costs. So looking for advanced control law and digital control is now the main stream. Under this background, the paper studies the Fuzzy Adaptive PID (FAPID) control method for platform stabilization loops.The platform stabilization loops are theoretically analyzed and compensated. The experimentation result of design and emulation argues that the conventional PID control is feasible. By designing the FAPID controller and doing the simulation, the result indicates that this method get a big improvement in the precision, respond speed and disturbance rejection.Direct Digital Control of platform stabilization loops based on DSP is investigated. The hardware and software are designed. In hardware design, TMS320F2407 is adopted as the base of controller. The relative circuitry is discussed. And in software design; the main process and subprogram are presented. DSP controller has the advantages in efficiency, speed and precision. TMS320F2407 is chosen as the core chip of the digital controller. It makes the motor control more convenient.
