<p>Methods for rapidly determining the discrete control information to independently propel a plurality of carriages with a synchronous linear motor divided into zones (138, 142, 146, 150) for control are useful for a steady state or a transition operation for a linear motor control system. The methods include the steps of representing the data describing the motion profile for each carriage in terms of memory address ticks versus linear motor primary teeth; determining the arrangement of data in a zone controller memory (128, 130, 132, 134) by performing a modulo operation on the profile motion data for each zone (138, 142, 146, 150); developing the overall motion profiles for steady state operation by defining and combining individual segments of motion curves using a variety of predetermined continuous analog relationships stored in a computer (100); and determining the data for the many intermediate transition curves between steady states by proportionately distributing data points for each intermediate transition curve between steady state data points, the proportion determined by a weighting function.</p> |
