It sent out a powerful radio signal that cut off the chatterer ' s cellphone transmission ? and any others in a 30 - foot radius 它发出了强烈的无线电信号，切断了说话人的手机信号- -以及其他人的- -在30英尺的半径内。
2.
Drawback occurred in the classical vssmc can be alleviated in the proposed control scheme because of importing the eliminating chatterer . according to the control strategy put forward above , corresponding controller for abs is designed . quarter braking vehicle model with four dof ( including vertical and longitudinal motions of body as well as vertical and spin motions of wheel ) is built considering the effects of wind resistance , longitudinal inertia forces , the vertical dynamics associated with the suspen 总之，基于车辆动力学建模，提出并探索了几种实用且具有高鲁棒性的变结构、模糊控制策略在abs 、 asr及vdsc系统中的应用，而后开发了abs的ecu原形，采用实时硬件在环仿真技术，对三种模糊控制策略进行了性能模拟。
