Abstract
A multi-axis Digital Signal Processor based servo controller system in which all servo and sensor interface boards are connected to a common backplane bus system enabling inter-board communication, with parallel processing using dual port memory and multiple DSP chips, and with each servo board having access to position data from other axis feedback sensors as well as their own, and a self-tuning control software architecture that uses the hardware architecture high speed to allow it to self-tune control constants to optimize performance.
