Abstract:For a class of multi-rate sampling linear batch process with disturbances and actuator faults, this paper presents an iterative learning fault-tolerant control algorithm with robust dissipative performances. The multi-rate sampling process is described by a state-space model with low sampling rate by using the lifting technology and based on the two-dimensional (2D) system theory. The iterative learning control process is transformed to an equivalent 2D Roesser system with structure-form faults;and then, the feedback fault-tolerant controller with dissipative performances is designed along the time and the trial directions. The sufficient conditions for the existence of the controller are given in terms of linear matrix inequalities (LMIs). Therefore, it can ensure the dissipative performances in normal and fault conditions for multi-rate sampling batch process. The injection velocity control simulations on the injection molding process demonstrate the feasibility and effectiveness of the proposed method.
