Design of Numeric Control Interpolation Compensation Algorithm Based on DSP

Abstract:

Using the TMS320C31 floating-point family DSP devices from the U.S. TI Company to have built the slave system for numeric control lathes. It makes full use of the advantages of TMS320C31 DSP, such as high-speed, high precision motion control in real time, to implement the linear and circular interpolation algorithms, sports section of acceleration and deceleration control content. Experiments show that: not only ensured the precision of digital control systems, and improved the interpolation of real time; solved the uniform allocation while any given pulse number in interpolation cycle; overcame the poor flexibility of original digital logic circuits of interpolation. Multi-axis control can be achieved to improve overall system performance. It’s with high practical value.
