This study was conducted to achieve high performance while reducing the computational complexity of MPC for autonomous vehicle tracking control. Previous studies have used a conventional linear time-varying MPC (LTV-CMPC) for the linear time-varying (LTV) vehicle model. For LTV-CMPC, the computational complexity increases exponentially as a predictive horizon and control horizon increase. Real-time implementation of LTV-CMPC with long horizons was difficult due to limited computational resources. For reducing computational complexity, we proposed LTV-MPC using Laguerre functions (LTV-LMPC). Considering the vehicle system, LTV-LMPC used a non-augmented model and described the input rate as Laguerre functions. The proposed LTV-LMPC significantly reduced the number of optimization variables. The number of Laguerre functions and the Laguerre pole determined the performance of the LTV-LMPC. In this study, we derived and proved propositions for analyzing the performance change of LTV-LMPC according to the Laguerre pole. LTV-LMPC with pole optimization (LTV-OLMPC) was proposed based on these propositions. The performance of the proposed algorithm was verified by simulation. The LTV-OLMPC guarantees low computational complexity and high performance. 收起
