Abstract
A system for actuating fluid flow is disclosed. The system includes a fluid actuator, an electric motor for driving the fluid actuator, a motor controller for controlling the motor, a local energy storage device for powering the motor, a stability monitor that assesses instability of operation of the fluid actuator, and a mitigation control that mitigates instability of the fluid actuator via the motor controller based on the assessment of the stability monitor, wherein a response time of the mitigation is faster than changes in fluid flow in the system during fluid actuation.

A system for actuating fluid flow comprising:
- a fluid actuator;
- an electric motor;
- a motor controller for controlling the motor;
- a supercapacitor for powering the motor;
- a stability monitor that assesses instability of operation of the fluid actuator;
- a plurality of sensors configured to provide spatially resolved instability information to the stability monitor;
