The invention relates to the technical field of medicine, and discloses a steering wheel controller system with a multi-degree-of-freedom motion platform, and the system comprises an input processing module which is used for receiving vehicle attitude data and steering wheel force feedback data provided by driving simulation software, and generating a rotation matrix of a platform attitude and a force feedback instruction of a steering wheel; and the optimization calculation module is connected with the input processing module, and is used for calculating the target attitude of the motion platform based on the rotation matrix of the vehicle attitude, determining the target stroke length of a plurality of electric cylinders on the motion platform, and carrying out optimization solution on the stroke of the electric cylinders. Through optimization calculation, real-time feedback control and modular design, high-precision reproduction and dynamic stability of the posture of the motion platform are achieved, the sense of reality of force feedback of the steering wheel is remarkably improved, and the problems that in the prior art, posture control is poor in real-time performance, dynamic errors are accumulated, feedback synchronism is poor and system expansibility is insufficient are solved.

    本申请涉及医药技术领域,公开了一种自带多自由度运动平台的方向盘控制器系统,包括:输入处理模块,用于接收驾驶模拟软件提供的车辆姿态数据和方向盘力反馈数据,生成平台姿态的旋转矩阵以及方向盘的力反馈指令;优化计算模块,与输入处理模块连接,用于基于车辆姿态的旋转矩阵计算运动平台的目标姿态,确定运动平台上多个电缸的目标行程长度,并对电缸行程进行优化求解。本发明通过优化计算、实时反馈控制及模块化设计,实现了运动平台姿态的高精度复现与动态稳定性,显著提升了方向盘力反馈的真实感,解决了现有技术中姿态控制实时性差、动态误差累积、反馈同步性差及系统扩展性不足的问题。
