摘要通過分析柴油機飛輪瞬時轉速的測量誤差，指出角度誤差是飛輪瞬時轉速的主要誤差來源，從而提出了減少誤差的方法，提高了瞬時轉速的測量精度。 -
The electro - hydraulic proportional control law is given. the laws of tracking control of displacement and speed of aircraft as well as tracking control of angle and angular speed of belt wheel are designed by means of state feedback linearization and quadratic performance index linear optimal control method. the robustness of the designed systems is analyzed, and arresting processes are simulated
給出了電液比例控制規律；利用狀態反饋線性化及二次型性能指標線性最優控制方法分別設計了系統跟蹤控制飛機位移與速度以及跟蹤控制帶輪轉角與角速度的非線性控制規律；對所設計的攔阻系統進行了魯棒性分析及攔阻過程模擬，模擬結果表明，通過選取適當比例系數或控制權系數，兩種控制系統的控制效果及魯棒特性均優于新型飛機攔阻系統。 -
It is discovered that the fluctuating increment of the instantaneous angular acceleration curve of crankshaft ( ay method ) put forward in this paper can be used to diagnose the power and compression condition of multi - cylinder engine in the state of shorter, more rigid crankshaft and lighter torsional vibration and in the rapidly diagnosed situation, and the ay method is better than the fluctuating increment of the instantaneous rotation speed curve of crankshaft ( n method ) which is used widely now
結果發現，在內燃機曲軸較短、剛性較大、扭振較小、對診斷速度要求很快的場合，用本文提出的曲軸瞬時角加速度波動增量j法能較準確地判斷多缸內燃機各缸的作功狀況和壓縮狀況，優于目前廣泛使用的曲軸瞬時轉速波動增量n法。 -
