“…Modeling each subsystem is key to simulate the entire system as closely as possible to its effective behavior. Integrating each subsystem model in a unique simulation environment is a fundamental step [17][18][19][20][21]. Complex, non-linear systems can be modeled by analytical or empirical approaches.…”

“…Power systems design is heavily affected by modern trends in energy saving. In the last few years, improving the power conversion efficiency becomes the key target, often sharply contrasting with system performances [1][2]. A tradeoff between pressing and conflicting requirements on power supply design is brought about.…”

The paper investigates the diagnosis of rotor broken bars in field oriented controlled (FOC) double cage induction motor drives, using current and vibration signature analysis techniques. The Impact of the closed loop control system cannot be neglected when the detection of asymmetries in the machine are based on the signature analysis of electrical variables. The proposed diagnosis approach is based on optimized use of wavelet analysis by a pre-processing of phase current or axial/radial vibration signals. Thus, the time evolution of the tracked rotor fault components can be effectively analyzed. This paper shows also the relevance of the fault components computed from axial vibration signal in comparison to those coming from phase current and radial vibration signals. Cyclic fault quantification, issued from the wavelet analysis, has been introduced for accurate rotor fault detection. Experimental results show the validity of the proposed technique, leading to an effective diagnosis procedure for rotor broken bar in double cage induction motor

“…Therefore, in most of existing digital controller for VRs [5][6][7][8][9], a high speed analog-to-digital converter (ADC) is required to improve VR transient response speed, thus to reduce the number of bulk capacitors. Moreover, to prevent limit cycle [10] and achieve tight voltage regulation, high resolution ADC and digital pulse width modulator (DPWM) are required, resulting in large silicon area and power consumption.…”

A novel digital adaptive voltage positioning (digital AVP) technique was proposed in [11]. Good transient performance had been achieved without using complicated control. In this paper, a small signal model is proposed for this mixed-signal digital controller. It is revealed by this small signal model that the inner current loop is in analog and the voltage loop is in digital, thus the controller can benefit from both: having valuable features of digital control but without limitations such as limit cycle. On the other hand, dynamic behavior of the voltage regulator with this digital AVP controller under large load transient is analyzed. With optimized bandwidth designed for switching stability, the VR with the digital AVP controller exhibits very excellent dynamic performance because of non-linear multi-mode control.
