“…As the control strategy of GTCC shown in Figure 13, the GT is calculated on the basis of the crank angle and the manifold pressure, which are obtained from the RE system. Since the motor output is normally limited due to magnetic saturation, 20 the output torque will be suddenly truncated (especially during the RE start phase) when a large motor torque is required. Hence, a torque compensation coefficient m is introduced to decide the value of the compensation torque.…”

One of the key challenges with the development of range extended electric vehicles is the noise, vibration and harshness behavior, specifically the uncomfortable ride experience during the range extender starting and stopping. This article focuses on providing an active control method to address this critical noise, vibration and harshness issue. A control-oriented nonlinear model for the start-stop vibration analysis, including range extender mount system, engine-clutch-motor shaft system, engine inertia torque and force, engine friction torque, engine gas torque, engine manifold pressure, electric motor torque and range extender controller, is thus built. In the developed model, a new estimation method for gas torque is proposed, where the initial crank angle is considered as well as the relevant equations are simplified. The method is proved to predict gas torque accurately without the expense of complex calculation process. Based on the model, the mount system vibration response has been analyzed that the excitation of range extender block on vehicle body in x-direction is the most prominent. The concept of the active control method, gas torque compensation control, is thus introduced in detail to reduce such a system vibration during start-stop phase. According to the control principle, the torque compensation coefficient for gas torque compensation control is determined and the compensation speed range is analyzed. In order to evaluate the control effectiveness, gas torque compensation control is implemented in the set-up model. The simulation outcomes demonstrate that gas torque compensation control is effective in reducing the vibration generated during start-stop transitions.

“…Like other drive systems, the performance of a PM motor drive also depends on the accuracy with which the parameters of the machine are known [8], [9]. Among these parameters are the stator phase resistances, the d-and q-axis inductances and the flux contribution of the permanent magnets.…”

Parameter identification of permanent magnet synchronous machines is a topic of utmost interest these days. The growing effort and investment in this field of research is largely due to the ever-expanding market share of these machines. The high-performance and efficient control of the drive depends on the accuracy with which the information about the machine connected to its terminals is available. The available identification methods are surveyed here and they are classified into offline and online strategies. Self-commissioning, in principle, is a subset of offline methods, yet it is treated separately for its importance in modern adjustable speed drives that tend to minimize the user intervention. Fully exploiting the power electronic converter and the computational power on-board a modern drive, the self-commissioning feature can be embedded in the start-up routine of the drive to estimate the parameters of the machine at hand. This paper presents a review of the parameter identification techniques and schemes investigated over the past few decades.

“…The core question to increase speed control performance is how to get a high-performance torque control method. In vector control strategy, a method often employed in PMSM drives, it is desirable to attain maximum torque per ampere (MTPA) ratio in order to achieve copper loss minimization [6]. In a surface mounted PMSM, MTPA ratio for constant torque region (below base speed) is accomplished by keeping d-axis current equals to zero.…”

The input current and voltage, at the control interface of permanent magnet synchronous motor (PMSM), are restricted by output ability from inverter. Focusing on PMSM vector control method, the paper analyzes the motor running status restricted by limit current and limit voltage from inverter under the dq coordinates. Combining with the control method of maximum torque per ampere (MTPA) and the flux-weakening control principle that eliminating back electromotive force (back-EMF), optimal-torque control method is developed. In the MTPA method, we can calculate the maximum output torque from the present speed. When the giving torque is bigger than the limit value, the voltage restriction will result that PMSM can not provide enough torque under the MTPA method. At this time, we adjust the current vector to make it reach the intersection point of voltage limit ellipse and the track of invariable output torque, which can take full advantage of output ability from inverter. The simulation results proved the superiority of optimal-torque control method in the case of high-speed and high-torque situation.
