Abstract In recent years, the rapid development of mechanical and electrical control technology promoting the research and application of mobile robots, more and more mobile robot used in our lives。 In addition, digital signal processors used in the field of motor control adding to the means of the motor control, and ti is promoting the development and application of mobile robots。this paper combines the motion control of the status quo, the omnidirectional mobile platform as the control object, the research on the digital signal processor as the core of the motion control system, including on hardware and software design of the control system, involving the main technical problems of analysis and research。
Through the analysis to the whole principle of motion and control mobile platforms and for the control of the DSP core motion control system analysis, we design of the whole program to the mobile platform control system based on DSP control technology, and related functions for analysis。
In this paper, the production of TI company DSP TMS320F28335 as the control core, and CDS5516 motor as the direct control of the object, combined with the sensor to achieve closed-loop control system。In the mobile platform control system hardware design, the main hardware circuit module of the DSP core board is designed, and the DXP Protel software is used to draw the PCB schematic, and ultimately establish a complete motion control system。 In the software programming part, this article uses the CCS3。3 programming software to carry on the programming and the debugging to the control system, and uses the oscilloscope to display the PWM pulse signal which we needs。
