Quantized filtering is one of the most important methods in networked information processing.The key problems of quantized filtering research are the quantization mode and the parameter selection strategies. Take the logarithmic quantization strategy as data transmission mode, this paper put forward a new quantized Kalman filter algorithm based on measured value, and two kinds of quantizer parameters...
This paper investigates the problem of OOSM filtering for the system with arbitrary-step-lag OOSM. A new direct OOSM filtering algorithm is devised, based on the built equivalent measurement. The proposed algorithm takes fully consideration on the correlation of the equivalent measurement noise and the previous estimations, so it is optimal in the sense of MMSE. Finally, a simulation with two scenes...
The embedded navigation system of autonomous underwater vehicle is introduced, which includes navigation overall architecture, hardware and software structure. The navigation system based on PC104 bus adopts the VxWorks system, which is a powerful real-time operating system. Intel PIIX-4 is used as the navigation controller's CPU. Meanwhile, the whole information flow of the navigation system is also...
Considering existing questions of the traditional synchronous fusion algorithms, e.g. assumptions of white noise and non-transmission delay produced by the influences of weather, humidity, magnetic field and communication line etc., the paper proposes an improved sequential weighted fusion algorithm, which cannot only deal with colored noise but also adapt automatically the case with network-induced...
