Because of the control complexity of the Parallel Kinematic Machines (PKMs), suchmechanisms may suffer from lack of accuracy at high speed. Unfortunately, conventional motioncontrollers have very limited flexibility because they are designed for Cartesian coordinates.Therefore, the motion control system for PKMs with both high performance and open architectureis urgently demanded. In this paper, an open architecture control system for PKMs based onmulti-DSP parallel procession is presented. Then, the hierarchical distributed control strategy isdiscussed in details. In addition, the realization of an interactive communication interface amongDSP processors is presented. According to the testing results, the developed system is capable ofobtaining an interpolation sampling period at least 3 times faster than that could be offered by mostcontrollers based on single-DSP, thus it is available for high-speed and high-accuracy control ofPKMs
