Chapter two introduces a few extensively used maneuvering models include constant velocity ( cv ) model, constant acceleration ( ca ) model, singer model, “ current ” statistical model and two - stage filter model, and discusses every model ’ s state function and parameters
第二章詳細介紹了目前運用最廣泛的幾種機動運動模型，包括勻速運動（ cv ）模型、勻加速運動（ ca ）模型、 singer模型、 「當前」統計模型和二級濾波模型;討論分析了各種模型的過程方程及各種參數。 -
Then novel circuit structure and circuit topologies family of current source ac / ac converters with high frequency ac link, based on flyback converter, are proposed. the circuit structure which can transfer one unregulated sinusoidal voltage with high thd into another regulated constant frequency sinusoidal voltage with low thd, is constituted of input cycloconverter, high frequency storage transformer, output cycloconverter, input and output filter. the circuit topologies family include single four - quadrant power switch mode, push - pull mode, half - bridge mode, and full - bridge mode circuits
本文提出了基於反激flyback變換器的電流源高頻交流環節ac ac變換器電路結構及其拓撲族，該電路結構由輸入周波變換器、高頻儲能式變壓器、輸出周波變換器以及輸入、輸出濾波器構成，能夠將一種不穩定劣質的正弦交流電變換成另一種同頻率穩定的優質正弦交流電壓；該電路拓撲族包括單四象限功率開關式、推挽式、半橋式、全橋式等四種電路。 -
The mixed control chip sg3525a combined with hardware pi controller generates the high - frequency pwm pulse for the first inverter. the digital control block tms320lf2407a mainly provides current preset for constant - current source through the outer filter, pwm pulse for the second inverter and drive signal for the high - frequency pulse power supply
其中變極性電源的一次逆變pwm信號由pwm發生晶元sg3525a ，配以外部硬體電路pi調節器產生;一次逆變閉環控制迴路的電流給定（配以外部濾波） 、二次逆變pwm驅動以及高頻脈沖電源的控制則由tms320lf2407a數字控制器實現。 -
As the system is regarded as being excited by a constant direct current at the data acquisition point, no complex ac circuit such as filter is required. it can improved the rate of data acquisition and simplify the circuitry of ert system
由於系統採用了直流脈沖信號作為系統的激勵源，后續的信號處理電路就可以直接獲得測量結果，無需復雜、耗時的濾波電路，這就消除了濾波器這一限制數據採集速度提高的「瓶頸」問題。
