Fast temperature prediction in laser assisted tape winding (LATW) process is a pivotal factor for having an in-line monitoring model. The interaction from the laser input to the output temperature should be fast enough considering the physics-based strategy. As the laser tape winding is a fast process (typically more than 100 mm/s) with very high-temperature increase rate, changing the texture of materials is expected during the heating process which causes changing in final output temperature. The model-based control system in this research includes a three-dimensional (3D) optical model to simulate the laser intensity distribution on the surfaces and a 2D quasi-state thermal model. The predicted heat flux distribution is used in the 2D quasistate fully implicit thermal model considering the advection term. Therefore, the procedure for calculating surface temperature can be performed in one computational step. Finally, the predicted temperature values can be sent to the PLC device via the ADS communication as a fast protocol to interact with the sensors and the industrial PC. The optimized laser intensity pattern, power, position and process velocity can then be calculated in the real-time.
