Research on Vehicle Adaptive Cruise Control Method Based on Fuzzy Model Predictive Control

نویسندگان

چکیده

Under complex working conditions, vehicle adaptive cruise control (ACC) systems with fixed weight coefficients cannot guarantee good car following performance under all conditions. In order to improve the tracking and comfort of vehicles in different modes, a fuzzy model predictive (Fuzzy-MPC) algorithm is proposed. Based on comprehensive consideration safety, comfort, fuel economy limitations, objective function constraints are designed. A relaxation factor vector introduced soften hard constraint boundary solve this problem, for which there was previously no feasible solution. maintain driving stability multi-objective optimization method, can update coefficient online, numerical simulation, values velocity, relative distance, acceleration change rate conditions compared, results show that proposed has better than traditional algorithm. The effectiveness reliability Fuzzy-MPC verified by co-simulation designed PID lower layer front feedforward feedback.

Adaptive Fuzzy Model-Based Predictive Control Using Fuzzy Decision- Making

Motivated by the need to develop more effective methods of controlling uncertain non-linear systems, this paper focus on developing an adaptive fuzzy model-based controller, in which the optimisation variables remain in the fuzzy domain. The scheme uses an on-line fuzzy identification scheme, which is able to generate a fuzzy relational model using the training data from the system. The propose...
