Closed Loop Control of Melt Pool Width in Laser Directed Energy Deposition Process Based on PSO-LQR
A closed-loop controller was proposed to adjust the laser power to maintain melt pool stability based on the linear quadratic regulator (LQR) control theory. The melt pool width acquisition system was built based on complementary metal oxide semiconductor (CMOS), and the captured melt pool image was...
