The paper presents a method for control analysis and design of roll-to-roll (R2R) dynamic system for printed electronics technology. The research provides an advanced control analysis and design methodology for a general multioutput multi-input (MIMO) strict-feedback class of nonlinear dynamic systems. The research starts with an integrator-backstepping control (IBSC) law formulation for the system by defining the modified tracking error in term of integral of normal tracking error. Considering each sublayer of control design process via a chosen Control Lyapunov function (CLF) and parameter assignment results in anIBSC law. Then, an IBSC law-based control strategy is provided for the design model. For the application of the proposed method, dynamic analysis on roll-to-roll (R2R) web system is made to transform a general nonlinear R2R web dynamics into a standard MIMO strict-feedback form for control analysis and design purposes. With the achieved model, an IBSC-based control algorithm is provided for numerical simulation and experiments. A control software is developed for implementing studies of numerical simulation and experiments to validate the reliability and feasibility of the proposed method.
