Abstract
In accordance with at least one aspect of this disclosure, a system includes, a servo configured to control a position of a valve, a driver operatively connected to control movement of the servo, a control module operatively connected to control the driver, can configured to control the driver with pulse width modulated output to control a frequency of a generator through movement of the servo.
Claims20
A system, comprising:
- a servo configured to control a position of a valve;
- a generator operatively connected to receive fluid from the valve;
- a driver operatively connected to control movement of the servo;
- one or more sensors operatively connected to sense and output a signal indicative of a frequency of the generator;
- and
- a control module operatively connected to control the driver, the control module configured to control the driver with pulse width modulated output to control the frequency of the generator through movement of the servo based at least in part on the signal indicative of the frequency of the generator.
3 more elements
A method comprising:
- sensing, with one or more sensors, one or more conditions of a servo;
- driving the servo to adjust a position of a valve with pulse width modulated output to control a frequency of a generator, wherein driving the servo comprises driving the servo with the pulse width modulated output based at least in part on the one or more conditions of the servo;
- and
- supplying flow of a fluid to the generator via the valve.
1 more element
A non-transitory machine readable medium containing instructions that when executed cause at least one processor to:
- drive a servo to adjust a position of a valve with pulse width modulated output to control a frequency of a generator, wherein the generator receives a flow of a fluid via the valve;
- wherein the instructions that when executed cause the at least one processor to drive the servo include instructions that when executed cause the at least one processor to drive the servo with the pulse width modulated output based at least in part on one or more conditions of the servo as sensed using one or more sensors.
