System Exposure
Why the system matters
Mobile hydraulic systems require stable position and force control despite oil temperature variation, supply pressure changes, valve deadband, and noisy field sensors.
ES-004 / Real-Time Control & Motion
Electro-Hydraulic Actuator Control Unit
Demonstrates how embedded compensation and diagnostics can improve actuator stability while reducing field tuning and troubleshooting effort.
