Encoder sinusoidal error compensation based on optimized PSO algorithm

Abstract

Encoders have the advantages of high precision and reliability, and are widely used in industries such as industry and aviation and military industries. As Industry 4.0 puts forward higher requirements for encoder output accuracy, this paper proposes a subdivision error compensation model of particle swarm network based on adaptive subdivision. Through the parallel iterative particle swarm optimization model, the error compensation of the encoder output grating signal is realized.The problems in the past particle swarm optimization models, such as slow convergence speed and easy to fall into local optimum, are optimized. The optimization algorithm can effectively improve the convergence speed and system accuracy of traditional particle swarm optimization.
