Embodiment Construction

[0018] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0019] A robot welding path planning method based on fireworks particle swarm algorithm, such as figure 1 shown, including the following steps:

[0020] Step S1: Use the greedy algorithm to initialize all path solutions and all control parameters of the population.

[0021] The specific method is as follows:

[0022] Step S1.1: Randomly select a welding point as the position Pwelding where the welding robot is located, and add the sequence of visited welding points;

[0023] Step S1.2: Search all the welding points that have not joined the visited sequence, find the welding point Pnext closest to the current welding robot position Pwelding, add it to the visited sequence as the current welding robot position. Repeat the above search until all the solder joints are added to the visited sequence, and a preliminary optimized indi...

Abstract

The invention provides a robot welding path planning method based on a firework particle swarm optimization algorithm, belonging to the technical field of robot welding control. The method comprises the following steps of: using a greedy algorithm to initialize all path solutions and parameters of the population; updating the speed and position of all population individuals according to the particle swarm operator; taking the individual of the particle swarm as a firework of the firework algorithm; generating sparks by modifying a blast operator and a Gaussian mutation operator; selecting firework populations by using an elite-roulette strategy; rebuilding the population by using a dual population strategy; and updating the individual historical optimal solution and the global optimal solution to obtain an optimal welding path. According to the robot welding path planning method based on the firework particle swarm optimization algorithm, the population diversity of the particle swarmis enhanced, information interaction among the firework algorithm individuals is achieved, and the optimal welding path is obtained by combining the particle swarm optimization algorithm with the firework algorithm, and the effectiveness and feasibility are high.
