This paper presents the design of a reconfigurable LPV controller for the Boeing 747-100/200 longitudinal axis The control objectives are to obtain decoupled flight path angle and velocity command tracking during normal operation and in the presence of an elevator failure. During normal operations, the controller uses the elevators and thrust for flight maneuvers. In case of elevator fault the control strategy uses th,e stabilizer as the alternative longitudinal control surface. Simulation results with elevator fault present show that the reconfigured controller stabilizes the faulty system.

The problem of robust fault detection in command inputs in the presence of modelling errors in linear time-invariant systems is addressed. The problem leads to a hypothesis test with a test statistic taking form of a weighted quadratic sum of independent normally distributed variables. It is rather difficult to compute the threshold for such a test and the corresponding error probabilities in an exact manner. Instead, the approximative results are derived by assuming assymptotic distribution of the test statistic towards normal distribution. Convergence conditions in case of growing number of summands are presented. Performance of the resulting detector is demonstrated on a simulated DC motor-generator rig.

Process manufacturing has some characteristics that makes it different from other types of industry. These specifics are reflected in the design of a process factory management system. This paper stresses some features of process manufacturing that have to be taken into account during the implementation of a production scheduling system.
