Claim 0:
1. A system for micro-object density distribution control with the aid of a digital computer, comprising:
one or more processors configured to execute computer-executable code, the processors configured to:
obtain one or more parameters of a system for positioning a plurality of micro-objects, the system comprising a plurality of programmable electrodes, the electrodes configured to induce a movement of the micro-objects when the micro-objects are proximate to the electrodes upon a generation of one or more electric potentials by one or more of the electrodes;
define a model describing a variation of micro-object density over time due to capacitance-based interactions based on the parameters of the system;
estimate a density distribution of the micro-objects using at least one sensor;
receive a target density distribution of the micro-objects;
perform model predictive control (MPC) optimization to derive based on the density model a sequence of the electrode potentials to be generated by at least some of the electrodes for moving at least some of the micro-objects to minimize an error between the estimated density distribution and the target density distribution;
actuate at least some of the electrodes to generate the sequence of the electrode potentials.
