Abstract
In various embodiments, a control system for an electronic circuit iteratively applies voltage to and senses current from a load to regulate operation of the load.
Claims38
A method for controlling, via application of first and second voltages, a circuit incorporating a load having a non-linear current-voltage relationship, the method comprising:
- (A) applying the first voltage to the load;
- (B) measuring a first current resulting from the first voltage applied to the load;
- (C) applying the second voltage to the load;
- (D) measuring a second current resulting from the second voltage applied to the load, a current difference between the second current and the first current having a magnitude;
- (E) altering the second voltage by a voltage increment having a magnitude and polarity based at least in part on the magnitude of the current difference between the second current and the first current;
- and
- (F) repeating steps (A)-(E) during operation of the circuit to regulate operation of the load notwithstanding any changes in the non-linear current-voltage relationship of the load during operation.

A method for controlling, via application of first and second inputs, a system incorporating a load having a non-linear output-input relationship, the method comprising:
- (A) applying the first input to the load;
- (B) measuring a first output resulting from the first input applied to the load;
- (C) applying the second input to the load;
- (D) measuring a second output resulting from the second input applied to the load, an output difference between the second output and the first output having a magnitude;
- (E) altering the second input by an input increment having a magnitude and polarity based at least in part on the magnitude of the output difference between the second output and the first output;
- and
- (F) repeating steps (A)-(E) during operation of the system to regulate operation of the load notwithstanding any changes in the non-linear output-input relationship of the load during operation.
