英文
phase step-
It really provides convenience to evaluate and optimize the design result. 3 ) vibration analysis has been fulfilled by calling some math libraries and graphic libraries in matlab to plot graphics such as velocity - time, displacement - velocity, step response, impulse response, gain - frequency and phase - frequency. we can know the capabilities of the spring system from the graphics
3 、在matlab環境下調用相應的數學函數庫和圖形庫對設計的彈簧進行分析，繪制彈簧加載后系統的速度-時間響應曲線、速度-位移響應曲線、階躍響應曲線、脈沖響應曲線、增益-頻率響應曲線和相角-頻率響應曲線，根據曲線來分析系統的各項性能。Secondly, image enhancement technique based on linear filtering is adopted. a new image segmentation method by means of automatic multilevel threshold is given, which realizes partial multilevel threshold segmentation based on image region partition of gray - level position projection, removes the influence of uneven illuminance or uneven gray - level distribution on goal recognition, and resolves the problem of error segmentation caused by threshold step between adjacent regions by threshold transition. the method has well robustness
在圖像處理時，採用基於線性濾波的圖像增強方法，並提出了一種新的自動多閾值圖像分割方法，該方法以基於灰度位置投影的圖像分區實現局部多閾值分割，克服了不均勻照明或不均勻灰度分佈對目標識別的影響，同時，通過閾值過渡很好地解決了相鄰區域閾值「階躍」引起的錯誤分割問題，具有很好的魯棒性。The key of the algorithm is identification of plant. based on analysis and calculation, the thesis presents the theory and method for minimum phase plant identification. the plant with uncertainty can be estimated through plant response to a short - duration step control effort acting directly on the plant so that the pdf control coefficients can be computed
該演算法最重要的是對對象的辨識，經過大量的分析與運算，本文提出了在對象為最小相位時，辨識對象的階數及其高階項系數的理論和方法，即以階躍信號直接激勵被控對象，對其輸出信號進行差分運算，利用所得的值判定對象的階數及其高階項系數。For the feedforward controller design, zero error characteristic of the step response of system with zero phase error tracking controller ( zpetc ) is proved and its application is studied
對於前饋控制器設計，證明了零相位誤差跟蹤演算法在階躍輸入下的無差性並研究了該特性的應用。分享友人
