The general objective is to maximize the performance of electric motor and generator drives using nonlinear and adaptive control techniques. A current project is focussed on induction generators, which are often found in renewable energy applications such as wind and hydroelectric sources. New results have been obtained regarding the operation of self-excited induction generators that operate off-grid. We are also studying nonlinear control methods for doubly-fed induction generators, which are typically used in wind farms, and squirrel-cage induction generators. On the left is a picture of a wind farm at the mouth of Spanish Fork, South of Salt Lake City. |

The objective is to develop methods for the cancellation of noise using speakers. The emphasis is on multi-channel systems and periodic noise sources of unknown frequency. The picture on the left shows an application to a propeller aircraft, where microphones are shown in green and speakers in red. Current research is aimed at developing algorithms that can adapt to changes in the properties of propagation of sound from the speakers to the microphones. |

Earlier research has developed reconfigurable flight control laws that automatically adjust their strategy after failures or damages (see, for example, the results of our flight tests). Recent research produces algorithms that optimize the use of multiple, redundant control surfaces (the so-called control allocation problem). In the example of the C-17 aircraft shown on the left, there are 16 control surfaces that can, potentially, be controlled independently. |
