The research of fuzzy immune linear active disturbance rejection control strategy for three-motor synchronous system

For the shortage of traditional Proportion Integration Differentiation (PID) in the application of the current multi-motor synchronous control system, this paper proposes a new control method which is fuzzy immune linear active disturbance rejection control (FI-LADRC) technology. The modern fuzzy immune control theory and active disturbance rejection control technology is combined for achieving the precise control of the three-motor synchronous coordination system. According to three motor synchronous system mathematical model, the whole disturbances compensation and the strong decoupling of the master motor speed and tension are achieved by the use of extended state observer (ESO). Moreover, nonlinear intelligent feedback is achieved by taking modern fuzzy immune control technology. Simulations and experiments show that: the control performance of the system is significantly better than the one of traditional PID control, such as good dynamic performance, obvious decoupling effect, strong anti-interference ability, high tracking accuracy, fast response and good robustness.
