Optimal Coordinated Control of Active Front Steering and Direct Yaw Moment for Distributed Drive Electric Bus

This paper suggests a hierarchical coordination control strategy to enhance the stability of distributed drive electric bus. First, an observer based on sliding mode (SMO) and adaptive neural fuzzy inference system (ANFIS) was designed estimate vehicle state parameters. Then upper layer primarily focuses coordinating active front steering (AFS) direct yaw moment (DYC). The phase plane method is utilized in this provide assessment basis for switching safety AFS DYC. lower designs integral terminal controller (ITSMC) non-singular fast (NFTSMC) obtain optimal additional wheel angle improve handling performance. A (FSMC) also proposed ameliorate stability. Finally, subjected simulation testing compared with performance DYC systems. evaluated tracking errors sideslip rate under two conditions. results demonstrate that can effectively adapt various extreme environments maneuvering
