FUZZY CONTROLLER WITH A REDUCED NUMBER OF SENSORS |
摘要 |
A control system for optimizing the performance of a vehicle suspension system by controlling the damping factor of one or more shock absorbers is described. In one embodiment, the control system uses a fuzzy neural network (1301). A teaching signal (1006) for the fuzzy neural network is generated using road signal data and a mathematical model of the vehicle suspension system. The teaching signal is used to develop a knowledge base (1302) for the fuzzy neural network. In one embodiment, inputs to the fuzzy neural network include damper velocities, heave acceleration, pitch acceleration, and roll acceleration. In one embodiment, the heave acceleration signal from the teaching signal is filtered to develop inputs for the fuzzy neural network, thereby reducing the number of sensors. In one embodiment, a Fourier transform analysis of the heave acceleration signal is provided to the fuzzy neural network. |
