stochastic disturbance meaning in English
随机扰动
Examples
- Simulation and computation results have shown that the optimal pid controller provides good control performance in terms of stochastic disturbance rejection , set - point tracking , and strong robustness . 4
仿真结果表明综合寻优得到的pid控制器在抑制随机干扰和设定值跟踪方面有良好的控制性能，也有很好的鲁棒性。 - Meanwhile , caused by the stochastic disturbances and measurement errors , monitoring model based on single measurement value of individual sampling time tends to lack credibility and stability , and can ' t reflect the overall phase - specific operation state
同时，由于各种随机扰动的影响及测量误差的存在，针对单一采样时刻的过程测量值进行建模往往不能保证足够的可靠性与稳定性，无法实时反映过程时段整体运行情况。 - The stochastic disturbance is brought to the deformable models and the simulated annealing is introduced to the iteration process . a new algorithm named sa snake ( simulated annealing snake ) is proposed . the algorithm has the ability to search globally
为了解决这个问题，我们在可变形模型中加入随机扰动因素，考虑在迭代过程引入模拟退火的思想，提出了一种称之为基于模拟退火的可变形模型sasnake ( simulatedannealingsnake )的新算法，算法具有全局搜索能力。 - Abstract : the most critical task in designing a model based on predictive controller is identifying a reasonably good process model . the identification model of mould level of a continuous casting line in a steel plant is very difficult . due to the extremely high stochastic disturbance level , well - known parametric identification methods using random step function , prbs or stochastic test inputs are not successful . the present method based on orthogonal test inputs gives satisfactory results
文摘:在设计一种基于预测控制器模型时，最关键的工作是识别一个合理可靠的过程模型.在钢铁厂的连续铸造线上识别铸模液位模型是很困难的，由于极高的随机干扰水平，使得众所周知的随机阶跃函数， prbs或随机试验输入等参数识别方法都以失败告终.而本文介绍的基于正交检测的方法给出了令人满意的结果 - Results of these researches indicate that adaptive control can efficiently reduce system ' s influences caused by model ' s uncertainties , stochastic disturbances , and quantified measuring noises . meanwhile , adaptive control can help the steering system acquire excellent performances of power - assisted and portability characteristics ; the suspension system has a good performance of reducing vibration , and can improve dynamical character of a full vehicle
