Human operator modeling based on fractional order calculus in the manual control system with second-order controlled element

The modeling for human operator behaviour is an important issue in the analysis and design for closed-loop manual control system, and the existing models for human operator are usually based on integer order calculus. In this paper, the manual control system with second-order controlled element is considered, and a kind of fractional order model for human operator is proposed. Based on the actual data, the effectiveness of the proposed model is validated, and the comparison results show that the proposed fractional order model is more suitable to describe the human operator behavior in the manual control process.
