Methods for controlling one or more positioning actuators and devices thereof

A computer readable medium having stored thereon instructions for controlling a moveable element comprising machine executable code which when executed by at least one processor, causes the processor to perform steps comprising:

• generating and providing one or more driving signals to one or more positioning actuators to move the moveable element towards a target position based on a target travel distance and a calibration value;
• determining when a post-movement position of the moveable element is outside of a tolerance range of the target position;
• recalibrating the calibration value when the post-movement position is determined to be outside of the tolerance range;
• and
• repeating the generating, the determining, and the recalibrating as open loop steps until the post-movement position is within the tolerance range.

A positioning system for a moveable element, the system comprising:

• at least one position sensor for monitoring a position of the moveable element;
• drive signal generation device;
• one or more positioning actuators coupled to the drive signal generation device and operatively coupled to the moveable element;
• and
• a control device coupled to the position sensor and the drive signal generation device, the control device comprising one or more processors and a memory coupled to the one or more processors, the one or more processors configured to execute programmed instructions stored in the memory comprising:
• generating and providing one or more driving signals to one or more positioning actuators to move the moveable element towards a target position based on a target travel distance and a calibration value;
• determining when a post-movement position of the moveable element is outside of a tolerance range of the target position;
• recalibrating the calibration value when the post-movement position is determined to be outside of the tolerance range;
• and
• repeating the generating, the determining, and the recalibrating as open loop steps until the post-movement position is within the tolerance range.
