Therefore, precise control of the hysteresis servo motor system is an urgent problem to be solved.
There are many hysteresis models in a hysteresis servo motor system at present, a pure physical model is a Jiles-Atherton model and the like, the physical model is closely related to actual physical parameters, and different materials or systems are not universal. More general hysteresis models are mathematical models, and commonly used models include Preisach models, P-I models, Bouc-Wen models, Backlash-like models and the like. The mathematical model has strong universality and wide application range, but the model is complex and has numerous parameters. The Backlash-like model is adopted, compared with other mathematical models, the Backlash-like model has relatively few parameters, and an analytic solution can be obtained.
Macki proposed a Backlash-like hysteresis model in 1993, described by a piecewise function, and g.tao further developed the model and proposed a model-based adaptive control algorithm. On the basis, the Chun-Yi Su formally changes the Backlash-like model into a current universal form, and provides a complete process of analytic solution. After that, the Backlash-like model becomes one of the important models for describing hysteresis. Recently, HeWei proposes an adaptive neural network control algorithm for a 3-degree-of-freedom robot hysteresis system, adopts two neural networks to estimate a dynamic system and hysteresis nonlinearity, and designs a high-gain observer to observe the state of the system. And Yu ZHaoxu designs a Backlash-like random nonlinear hysteresis system controlled by an adaptive neural network controller based on an input-drive observer according to a Nussbaum gain function. The inventor also researches preset precision self-adaptive control based on a Backlash-like hysteresis model, converts vector errors into scalar errors by adopting a Laplace variation method, provides a new preset precision function, and designs a model reference self-adaptive controller control system.
