Understanding human drivers' behavior is critical for the self-driving cars, and has been intensively studied in the past decade. We exploit the widely available camera and motion sensor data from car recorders, and propose a hybrid method of recognizing driving events based on the random forest approach. The classification results are analyzed by comparing different features, classifiers and filters...
To improve the dynamic performance of the dual PWM converter, a new control strategy named direct capacitor power control based on sliding mode variable structure (SMC-DCPC) was proposed. In order to control the capacitor power and the grid-side reactive power to be zero, two sliding mode controllers were designed in the inner power loop. To realize the decoupling of grid-side active power, load power...
With the method of instantaneous symmetrical components, positive, negative and zero sequence components can be gained. The traditional instantaneous symmetrical components are usually implemented under dq0 synchronization reference frame on condition that low-pass filter is adopted in, which causes aggravated dynamic performance. To solve this problem, this paper presents a novel algorithm of instantaneous...
In this paper, an improved predictive current controlled three phase voltage source pulse width modulation (PWM) rectifier was described. This method was based on the discrete mathematical model. The desired ac-side current was predicted according to minimizing power errors target function in a fixed time interval. This control system realized fast tracing by selecting switching states based on the...
