摘要

为实现较高速行驶情况下驾驶机器人驾驶车辆进行横向轨迹跟踪，设计了一种基于动态杂交粒子群算法求解的非线性模型预测控制器。首先，简化转向机器人与车辆转向系统，建立车辆动力学模型。其次，应用双参数精确罚函数法将非线性有约束优化函数转换为非线性无约束优化函数。在此基础上

将驾驶机器人作为下层控制器，应用动态杂交粒子群算法对优化函数进行求解。最后，基于Simulink/CarSim和RT-LAB硬件仿真，验证了改进的模型预测控制器具有较高的跟踪精度和行驶平稳性。

Abstract

In order to drive a vehicle using driving robot for lateral trajectory tracking at higher speed

a nonlinear model prediction controller based on the dynamic hybrid particle swarm algorithm solution is designed. Firstly

the steering robot and vehicle steering system are simplified

and the vehicle dynamics model is established. Then

the two-parameter precision penalty function method is used to convert the nonlinear constrained optimization function into a nonlinear unconstrained optimization function. On the basis of these above

the driving robot is used as the lower controller

and the dynamic hybrid particle swarm algorithm is used to solve the optimization function. Finally

based on the Simulink/CarSim and RT-LAB simulation

the improved model prediction controller is verified to have high tracking accuracy and driving smoothness.
