Abstract

A procedure for the design of reduced order observers for state estimation and instrument fault detection is described. Advantages of using a special canonical form of the system and deriving the observers by two instruments are demonstrated and the feasibility of using the observers in a Dedicated Observer Scheme is established by computer simulation studies on a 14th order model of a Puma helicopter. These studies indicate that scale-factor, dead-zone and bias faults in the sensors may be detected as they occur when maintaining an accurate estimate of the state. Areas for further analytical work, including sensitivity analysis and tolerance to parameter variations, discussed.
