Sensor-Free Prediction Method Guards Stirling Generators Against Piston Overshoot Damage

Tokyo, Japan (SPX) Apr 30, 2026

Researchers have developed a fast prediction and suppression method for transient piston displacement overshoot in free piston Stirling generators, addressing a fault condition that can quickly escalate into mechanical damage in solar thermal power systems. The new approach detects dangerous overshoot without relying on displacement sensors and suppresses the fault response early enough to maint
