Control Research of Three-Axis Turntable Based on Neural Network Inverse System

For the nonlinear coupling characteristics between three axes of the three-axis turntable, a method which combines the inverse system method and Neural Network (NN) has been put forward. This method realizes linearization and decoupling of three-axis turntable and solves the defect of difficult to realize precise decoupling with inverse system method when the model of three-axis turntable is inaccurate. Simulation results show the feasibility of the method and also good robustness and resistance.
