The increasing complexity of modern engineering production systems and requirements for high quality products have created a need for control systems with fault-tolerance. This chapter presents two algorithms for fault-tolerance analysis and fault-tolerant controller design. In Section 6.2, a model-based fault detection and fault-tolerant control technique for a pressurized headbox is presented. The sensor failures are detected and then located. The controller and state estimator are automatically reorganized subsequently to the occurrence of the failures to ensure the stability and acceptable performance of the closed loop system. In Section 6.3, a linear quadratic optimal system with the highest fault-tolerance is developed for the drying section. Quantitative relationship between fault-tolerance and controller designing parameters are established. An iterative algorithm is proposed to design control system with the highest fault-tolerance.
