The design of the seam tracking sensor is the key work in the realization of the welding automatization. A novel touch photoelectric sensor for seam tracking was designed on the base of getting over the shortcoming of non-touch seam tracking sensor and using the principle of the photovoltaic translation. The idler pulley can touch the seam closely, then the sensor can realize the auto-tracking by the oriented function of the groove. If the offset of the idler pulley location appear, the sensor can change the offset to the voltage using the cell of the photovoltaic translation and the cell of signal processing.

According to this understanding, this thesis tries to modify PSO algorithm in order to improve its quality of solutions. The main approches include: using uniform design to ensure the uniform distribution of initial particles in the design space; adding mutation operation to increase the diversity of particles; decreasing the maximum velocity limitation and the velocity inertia automatically to balance the local and the global search efforts; developing a new approach to treat the design variables exceeding the bounds; using extensive local searches to escape local minimum. The overall effect of these approaches can yield better results for most test problems.
