The parameters of suspension system cannot change according to the road excitation, and the system can only store or exhaust the body vibration energy. The active suspension system can improve both the riding comfort and handing safety in various operation conditions. The least means squares adaptive algorithm is used in active suspension system. For the least means squares adaptive algorithm, the...
A kind of active suspension system combined with passive suspensions and active components is addressed. Suspension dynamics are modeled using a two degree-of-freedom, linear and time-invariant vehicle model. The least means squares adaptive algorithm that guarantees system optimal control, is presented and used to find the optimal suspension system design. For two-DOF vehicle suspension model, LMS...
An adaptive fuzzy controller which fuzzy control rule table can be obtained with the numerical calculation is designed in order to improve vehicle comfort and road holding capability. There is no membership function choice of fuzzy subset for input and output of controller. The rectification factor is adjusted online according to adaptive method. The factor can be influenced by exciting signal and...
To improve vehicle comfort and road holding capability, an adjustable fuzzy control algorithm which fuzzy control rule table can be obtained with the numerical calculation is advanced. Because the algorithm can adjust the rectification factor of fuzzy controller, it not only can reflect the advantage of fuzzy logic in nonlinearity system but also can improve the disadvantage of common fuzzy control...
