Latest Patents
John Sandell holds a patent for the "Synchronization of multiple axes in a motor drive." This patent describes a motor controller that executes an axis module for each of multiple motors coupled to a shared load. The first control module passes at least one state variable to a second control module without experiencing communication delays between the axis modules. To decouple interaction between axes, the first control module determines the desired state variable at a periodic update rate and stores it in memory. The first control module then provides an indication to the second control module that the desired state variable is available. Within the same period, the second control module receives this indication and reads the state variable from the memory of the controller. This innovative approach reduces coupling between the two control modules, enhancing overall system performance.
