【 摘 要 】

This paper solves data-based simultaneous fault detection and control (SFDC) problem for a multivariable laboratory process named quadruple tank process which has an adjustable zero that can be located in both left and right half-plane. The knowledge of mathematical model of the process is not needed and only input/output time domain data (I/O) are used for solving a data-based H_infinity optimization problem. Solving this problem yields a easily implementable design algorithm for data-driven H_infinity controller/detector unit of modest complexity that is able to achieve some control and fault detection objectives. The tradeoff between these objectives is established by tuning a scalar parameter and some weighting matrices. The effectiveness of the proposed methodology is demonstrated for both minimum phase and non-minimum phase plants in the presence of both incipient and abrupt faults.
