Title The design of the intelligent stability control system
Abstract
The three-dimensional stable platform can isolate the impact of changes from movement and posture, and it can keep level to the earth and track the target, which is widely used in modern weapons.
This paper focuses on the three-dimensional stable platform for simple structure design and corresponding control research, introduces the stability platform system structure and working principle .The design of the three-dimensional steady platform includes primary stabilization platform and fine stable platform .The primary stability platform has two degrees of freedom from lateral sway and longitudinal shake .It analyzes the changes of the nut screw torque and the motor speed and power. According to the platform rotation angle of the rotation frequency ，it determines the size and scope of the required maximum motor torque and speed ,and selects the appropriate hardware. The latest DSP chip TMS320F28335 is selected as the development board. Choose PID algorithm respectively to control the motor work. When the platform turned to an angle, the motor drives screw to rotate to the reverse direction ，until the platform recovery level .Fine stable platform has two degrees of freedom from longitudinal Shake and rotary ,in which the longitudinal Shake system is composed of gear transmission to realize, rotary system is composed of worm gear and worm drive to achieve. In this paper only carries out overall design and motor selection.
Keywords Stable Platform Stepper motor PID controller DSP
