【Abstract】 The research of tilting train in our country has been in the stage of practicality. The main content of this paper is about sensor’ fault-detection, and the correlative signal processing algorithms, providing the control system with accurate and reliable uncompensated signal filtering-delay-compensation signal. The sensor’ fault-detection is studied, so do the three variance-calculating methods for sensors’ fault-detection. All the derivation and realization processes of the these algorithms are discussed in detail. All the algorithms presented in this paper are simulated through the data gained in the test-on-line. The C program to realize the optimal can be easily transferred to DSP system, it performs well in the DSP system designed for tilting train, and it has also passed the preliminary test in the test on line.更多还原
