Because there is a dynamic tuning to the prediction error in the controller design, and the proportional integration type cost function is used, so the controller has strong robustness to unmodelled dynamic. 由于在控制器的设计中,进行了预测误差的动态校正,并且控制器采用了比例积分型(PI)目标函数,因...
The effect of repeated local ischemia and reperfusion on myocardial metabolism and ventricular performance was studied in 12 open-chested pigs fasted overnight. Myocardial ischemia was induced by reduction of the flow in the left anterior descending coronary artery to 40% of control during 30 min. ...

In time-based control, the feedback voltage from the power regulator output is applied to a voltage-controlled oscillator (VCO) and compared with a reference oscillator, and the phase difference between the two, computed using a phase detector into a PWM signal, are used to control the power...
First, based on the broadband that is typical of blast waves, the peak frequency of the P-wave was obtained in the time–frequency domain, taking advantage of the difference in the propagation speed of the P-wave, S-wave, and the surface wave. Second, the phase difference between two ...
