鑿巖機(jī)器人鉆臂定位控制交叉精英反向粒子群算法
[Abstract]:In the process of drilling robot arm localization using particle swarm optimization (particle swarm optimization,PSO), there are some problems such as slow convergence speed and easy to fall into local optimal solution. Therefore, a cross-elitist reverse particle swarm optimization (crossover elite opposition-based particle swarm optimization,CEOPSO) algorithm is proposed and the flow of the algorithm is given. The kinematics model of drill arm of rock drilling robot is established and its inverse kinematics is solved. The crossover operator is introduced into EOPSO, and adaptive inertial weight and crossover probability parameter control techniques are adopted to increase the information exchange between particle individuals and optimal solutions on the basis of maintaining information exchange between particle individuals and optimal solutions. The algorithm improves the global searching ability and the efficiency of drilling arm location. The simulation results show that the average position error and the average attitude error of CEOPSO are smaller than those of PSO and EOPSO algorithms, and the iterative process is stable, which can effectively improve the positioning control performance of drilling arm of drilling robot.
