Title:
ADAPTIVE CONTROL OF FREE PISTON MOVER OPERATION
Document Type and Number:
WIPO Patent Application WO/2020/128515
Kind Code:
A3
Abstract:
Adaptive control of a Free Piston Mover (1, 19), wherein a Control Parameter Set (COPS') for closed loop control of a Target Control Variable (CVt) is adapted using a Future-Stroke Controller (20) to respond to Input Demand (21) signals whilst ensuring a sufficient current control margin and compensating for system changes over time. The Control Parameter Set (COPS') is transmitted to an In- Stroke Controller (23) in advance of the start of a stroke to be controlled, and the In-Stroke Controller (23) transmits a Current Demand (Qt) to a Current Controller (25) of the Free Piston Mover (119).
