Robust vision-based controller design for laser cladding processes

摘要: In practical cladding processes, any small parameter variation may cause undesired geometry changes. Therefore, a fast and robust controller design is required to ensure the quality of process. this paper, vision-based with specified interval phase-margin performance for laser processes presented. First, nonlinear was modeled as fuzzy parametric uncertain model. A α-cut representation used describe parameters By using generalized Kharitonov theorem, PI can be obtained from graphic k P - I plane. The simulation results validate that proposed not only different operating conditions, but also exhibits better dynamic response.
