Adaptive strategy with output constraints for multi-section web linkage system

Solving unpredictable fluctuations in tension and speed is essential for optimizing the material transportation process of web materials linkage systems. We develop an adaptive controller to control the output values and restraint tension values within a specific range of requirements. External disturbances existing in this nonlinear system are estimated by the radial basis function neural network (RBF NN), while tension output constraints maintenance and stability of object are both guaranteed by Barrier Lyapunov function (BLF) analysis. The superiority of the proposed controller compared with other nonlinear controllers is verified through simulation.
