Abstract
A distributed control system may include a main processing unit, a distributed control module, and a controllable component. The distributed control module may be configured to receive a nominal command reference from the main processing unit, determine a series of cumulating command references based at least in part on the nominal command reference; and output a series of cumulating control commands to the controllable component. The series of cumulating control commands may be based at least in part on the series of cumulating command references.
Claims19
A method of controlling a controllable component of a turbomachine, the method comprising:
- receiving a nominal command reference from a main processing unit;
- determining a series of cumulating command references based at least in part on the nominal command reference;
- and
- wherein determining the series of cumulating command references comprises:
- determining a command reference reciprocal (K), wherein the command reference reciprocal (K) represents a real number;
- determining a series of K(t)-incremental command references sequentially corresponding to one of (K)-increments of a DCM unit time interval (t), wherein the DCM unit time interval (t) represents a unit of time of a DMC clock, and wherein the series of K(t)-incremental command references represents the (K)-increments as a function of the DCM unit time interval (t);
- and
- determining a series of K(t)-cumulating command references sequentially corresponding to one of the (K)-increments of the DCM unit time interval (t), the series of K(t)-cumulating command reference determined based at least in part on the series of K(t)-incremental command references;
- outputting a series of cumulating control commands to the controllable component of the turbomachine, the series of cumulating control commands based at least in part on the series of cumulating command references, the controllable component including at least one of a variable-geometry component, an actuator operably coupled to the variable-geometry component, and a servo-actuator coupled to the variable-geometry component, wherein outputting the series of cumulating control commands to the controllable component of the turbomachine effects control of the controllable component.
A distributed control system, comprising:
- a main processing unit, a distributed control module, and a controllable component of a turbomachine, the distributed control module including at least one of a processor, a memory, and an interface, the controllable component including at least one of a variable-geometry component, an actuator operably coupled to the variable-geometry component, and a servo-actuator coupled to the variable-geometry component, the distributed control module configured to:
- receive a nominal command reference from the main processing unit;
- determine a series of cumulating command references based at least in part on the nominal command reference;
- determine a series of cumulating control commands based at least in part on the series of cumulating command references;
- and
- output the series of cumulating control commands to the controllable component;
- to effect control of the controllable component.
A non-transitory computer readable medium comprising computer-executable instructions, which, when executed by one or more processors of a distributed control module, cause the distributed control module to:
- receive a nominal command reference from a main processing unit;
- determine a series of cumulating command references based at least in part on the nominal command reference;
- determine a series of cumulating control commands based at least in part on the series of cumulating command references;
- and
- output the series of cumulating control commands to a controllable component of a turbomachine, the controllable component including at least one of a variable-geometry component, an actuator operably coupled to the variable-geometry component, and a servo-actuator coupled to the variable-geometry component, wherein output of the series of cumulating control commands to the controllable component effects control of the controllable component.
