This paper proposes a new intelligent control strategy to meet the tracking requirement of the power itself considering the coupling impacts of the plasma cutting technology. The dynamic intense coupling impacts of the technologies can’t be simulated, and a novel style of PID neural network (PID-NN) is applied to obtain closed-loop controller’s reference cutting current via its nonlinear mapping effect. The PID algorithm parameters are self-adjusted through fuzzy logic, whose inputs are both the reference current error and its variation rate. Simulation and testing experiments have verified the greater improvements of this project in steady precision, response speed and robustness, and the controller’s advantage in dealing with discrete events and multivariate decoupling problems.
