Then the parameter auto-adjusting fuzzy-PID control method was used by adjusting the three parameters of PID to control the varying errors for the longitudinal relative distance and relative velocity between the controlled vehicle and the navigation vehicle. 应用参数自整定模糊-PID控制,对PID的3个参数进行调节,控制被控车与导航车的车间纵向相对距离误差和纵向相对速度误差的变化范围,以实现汽车纵向控制。
Based on a zero sideslip angle proportional control, we get the gain of the distance from the centroid to the steering center position, yaw angular velocity and lateral acceleration. 在此基础上,得到车辆采用零侧偏角控制策略时,车辆转向中心到质心的距离,横摆角速度增益及侧向加速度增益的表达式。
According to the technological documents of direction control blasting in our country, it is neccessary to consider the action of air resistance in the computation for the throwing distance by applying the initial throwing velocity and projectile theory. 本文根据我国定向爆破工程技术资料,认为应用抛掷初速度及弹道理论来计算抛距时,必须考虑空气阻力的作用,提出一套定向爆破抛距计算公式。
