SVPWM是近年发展的一种比较新颖的控制方法,是由三相功率逆变器的六个功率开关元件组成的特定开关模式产生的脉宽调制波,能够使输出电流波形尽可能接近于理想的正弦波形。空间电压矢量PWM与传统的正弦PWM不同,它是从三相输出电压的整体效果出发,着眼于如何使电机获得理想圆形磁链轨迹。SVPWM技术与SPWM相比较,绕组电流波形的谐波成分小,使得电机转矩脉动降低,旋转磁场更逼近圆形,而且使直流母线电压的利用率有了很大提高,且更易于实现数字化。(SVPWM is a novel control method developed in recent years. It is a pulse width modulation wave generated by a specific switching mode consisting of six power switching elements of three-phase power inverters, which can make the output current waveform as close as possible to the ideal sinusoidal waveform. Space voltage vector PWM is different from traditional sinusoidal PWM. It is based on the overall effect of three-phase output voltage, focusing on how to obtain the ideal circular flux trajectory of the motor. Compared with SPWM, the harmonic component of winding current waveform is smaller, which reduces the torque ripple of motor, makes the rotating magnetic field more close to the circle, and improves the utilization ratio of DC bus voltage greatly, and makes it easier to realize digitization.)

模型预测电流控制其控制思想基于以下原理:首先,功率变换器产生的开关状态个数有限,且通过建立模型可以预测每一个开关状态下被控变量的对应变化特性;其次,定义价值函数评价被控变量的预测值,为判别最优有限开关状态提供依据;最后,计算出每一种开关状态下的价值函数值,以此评价每一种开关状态下被控变量预测值的优劣,选择出最优的开关状态并应用。(The control idea of model predictive current control is based on the following principles: firstly, the number of switching states produced by power converter is limited, and the strain characteristics of controlled variables under each switching state can be predicted by establishing a model; secondly, the value function is defined to evaluate the predicted values of controlled variables, which provides a basis for judging the optimal finite switching state; lastly, the optimal finite switching state is calculated. The value function value under switching state is used to evaluate the predicted value of controlled variables under each switching state, and the optimal switching state is selected and applied.)

演变过程 自抗扰控制器自PID控制器演变过来,采取了PID误差反馈控制的核心理念。传统PID控制直接引取输出于参考输入做差作为控制信号,导致出现响应快速性与超调性的矛盾出现。(In the process of evolution, ADRC evolves from PID controller and adopts the core idea of PID error feedback control. Traditional PID control directly draws the output from the reference input as a control signal, which leads to the contradiction between response speed and overshoot.)
