Abstract
A system and method for calibrating fluid detects an actual fluid dispensing characteristic, such as dispensing speed, and automatically adjusts the dispensing characteristic to match an ideal dispensing characteristic. The adjustment is conducted by a controller that controls fluid dispensing based on a function that correlates dispensing speed, a dispensed volume, and a dispensing time. The function allows calibration to occur automatically by converging system operation to the ideal dispensing characteristic, without requiring a user to calibrate the system through manual iterative methods.
Claims19
A fluid calibration system, comprising:
- a fluid dispenser;
- an actuator coupled to the fluid dispenser that controls output of a fluid from the fluid dispenser, and
- an actuator control coupled to the actuator, wherein the actuator control automatically adjusts the actuator based on a difference between an actual dispensing characteristic and an ideal dispensing characteristic and according to a function.
A fluid calibration system, comprising:
- a fluid dispenser;
- a motor coupled to the fluid dispenser that controls output of a fluid from the fluid dispenser,
- an motor control coupled to the actuator, wherein the motor control automatically adjusts the motor based on a difference between an actual dispensing speed and an ideal dispensing speed and according to a function based on at least one of a fluid dispensing time, dispensing speed, and dispensed volume, wherein the actual dispensing speed is determined by obtaining an elapsed time for obtaining a target dispensed volume;
- and
- a memory accessible by the motor control.
A method for calibrating a fluid dispensing system, comprising:
- detecting an actual dispensing characteristic of a fluid dispenser controlled by an actuator;
- determining a difference between the actual dispensing characteristic and an ideal dispensing characteristic;
- and
- controlling the actuator based on the determined difference and according to a function based on at least one of a fluid dispensing time, dispensing speed, and dispensed volume to obtain the ideal dispensing characteristic.
