Besides, pid control algorithm is introduced and the velocity closed - loop controller is designed on the basis of dynamic model for the train. furthermore, according to kunming world ' s fair route data, the ato system with pid controller is simulated. it shows some disadvantages, and so the predictive control algorithm is brought forward to realize velocity closed - loop control
在已有的列車運動模型基礎上,採用pid控制演算法,設計了列車的速度閉環控制器,結合昆明線線路數據,進行了基於pid控制器的ato系統模擬分析,發現採用pid控制器控制時,列車運行曲線呈波浪形,當遇到坡道或者外界干擾時速度和加速度曲線會出現尖峰現象。Dbf algorithms for 2d planar array based on the algorithms for 1d array are discussed in this paper. the author ' s main contributions include research of the adaptive digital beamforming algorithm, which control both amplitude and phase of each array element : diagonal loading qrd - smi algorithm. research of two phase - only dbf algorithms : small phase perturbation restriction algorithm and maximum gain of the expected direction restriction algorithm
