“…The results in controller design can be briefly classified into two categories: linear design and nonlinear design. The classical voltage-oriented control in rotating coordinates [6]- [10], which is a linear design method, becomes a standard solution in industrial applications [25]. However, with a linear controller, both the stability and the performance of a VSR cannot be guaranteed under a wide-range rapidly varying load [26].…”

The aircraft electric actuator is one of the most important kind of electric loads of the future more electric aircraft. The power characteristic of an aircraft electric actuator possesses the feature of rapidly varying in a wide range, and it shows constant power load nature in the small-signal sense. In this paper, a novel dc-bus voltage switched control method of three-phase voltage source pulsewidth-modulated rectifiers (VSRs), which aims to solve the problem of flexible voltage regulating under dynamic loads, is proposed under a cascade structure in rotating synchronous coordinates d−q. Several linear controllers are designed on different operating points of the VSR, and one controller is implemented on the VSR system according to certain switching law. The stability of the proposed control approach is guaranteed based on the common Lyapunov function method. Simulation and experimental results show that the desired control performance is obtained in the voltage regulating of a VSR with wide-range rapidly varying load. Compared with a classical PI controller, the derived switched controller can achieve a considerable reduction in the dip of the dc-bus voltage and a certain reduction in the overshoot of the dcbus voltage during the control process under an aircraft electric actuator load.

“…The sinusoidal PWM, optimal PWM and spacevector modulation are used in these controllers which yield constant switching frequency. Non-linear current control group includes hysteresis current controller (HCC) [1], fuzzy logic based controller [27,29] and neural network based controller [17,32,46], etc. The main advantages of neural network based controllers are parallel processing, learning ability, robustness, and generalization.…”

“…It is well established that conventional fixed gain linear proportional-integral (PI) and proportional-integral-derivative (PID) controllers are widely used in most industrial power electronics applications thanks to their simplicity and feasibility [9,10]. Several control schemes based on linearization methods are also proposed to achieve a fast dynamic response to load and line disturbances in [11][12][13].…”
