Artificial intelligence techniques such as artificial neural networks and fuzzy logic are now essential tools in the design of a variety of control systems. These techniques are being employed either to form an integral part of a hybrid control strategy or in the formulization of a stand alone robust control algorithm. For several years control schemes based on fuzzy rule bases have proven to be very successful in several fields of study from a practical viewpoint. However, the major drawbacks with this approach are in the development of the linguistic fuzzy rule bases and their optimization. Heuristic, self-organizing and adaptive search methodologies have been exploited by the AMS Research Group to overcome these shortcomings in the design of fuzzy controllers.
The performance of any control scheme, of course, is governed by the quality of the input signal it receives. For many years linear and extended Kalman filters have been the popular choice for obtaining the best signal estimate from sensor data that has been contaminated with noise. Kalman filters are also widely used in the formation of multi-sensor data fusion (MSDF) algorithms.
In the design of conventional Kalman filters significant difficulties can arise owing to incomplete a priori knowledge concerning their process noise covariance and measurement noise covariance matrices. For most practical applications, these matrices are initially estimated and fixed.
Therefore, the problem which has to be overcome is the optimality of the estimation algorithm in a Kalman filter setting as it is closely connected to the quality of a priori information about the process and measurement noise. It has been shown that insufficiently known a priori filter statistics can reduce the precision of the estimated filter states or introduce biases in their estimates. In addition, incorrect a priori information can also lead to instability in the filter algorithm. To surmount such problems, AMS has developed adaptive Kalman filter designs using fuzzy logic and genetic algorithms that regularly update the aforementioned matrices.
Adaptive fuzzy Kalman filters are also being developed by AMS for use in MSDF algorithms. MSDF may be described as the acquisition, processing and the synergistic combination of sensor information to provide a more comprehensive understanding of the phenomenon being monitored. Owing to the availability of data from multiple sensor sources, uncertainty can be reduced, noise rejected and sensor failure tolerated as a result of built in redundancy.
All the above techniques have been and are being actively researched and applied in a number of marine and industrial applications.
