“…The analysis of the chaos behavior in the closed-loop drive system of IM is performed using Poincaré mapping and linearization tools. 10 This paper shows that, unlike previous studies, chaotic behavior in this drive system occurs assuming the inverter is ideal, in closed-loop and open-loop systems. Also, unstable areas on the voltage-frequency plane change between closed-and open-loop systems.…”

“…These studies can be divided into two parts: analysis and control of chaotic behavior in these systems. In the field of chaos behavior analysis of various types of electric drive systems, most of the work has been carried out in References 8‐17 The open‐loop IM drive system is modeled using eight differential equations in a nonlinear form, taking into account the motor, mechanical load, voltage inverter, and rectifier 8 . In Reference 9, this open‐loop system uses a voltage‐to‐frequency scalar control to adjust the speed, in the presence of constant and periodic load.…”

In this paper, a nonlinear dynamic of permanent magnet synchronous machine scalar drive systems (PMSMSDS) is investigated thoroughly. At first, the mathematical dynamic model of the PMSMSDS is developed and formulated for open-and close-loop cases. Then, constant and periodic load torque are considered for the analysis of the system. The Jacobian matrix and the Poincaré mapping of the system are calculated analytically to study the feasibility of nonlinear phenomena at each point of equilibrium for constant and periodic loads, respectively. Computer simulation is used to obtain bifurcation diagram, time response, and phase plane of the state variables to investigate the complex behavior of the system by changing some parameters. It is shown that by changing the parameters of reference speed command, supply voltage range, and speed controller gain, the response of PMSMSDS state variables will be routed to limit cycle, bifurcated, and chaotic. Numerical analysis is provided to confirm the simulation results.

Abstract-Power electronic converters enable wind turbines, operating at variable speed, to generate electricity more efficiently. Among variable speed operating turbine generators, permanent magnetic synchronous generator (PMSG) has got more attentions due to low cost and maintenance requirements. In addition, the converter in a wind turbine with PMSG decouples the turbine from the power grid, which favors them for grid codes. In this paper, the performance of back-to-back (B2B) converter control of a wind turbine system with PMSG is investigated on a faulty grid. The switching strategy of the grid side converter is designed to improve voltage drop caused by the fault in the grid while maximum available active power of wind turbine system is injected to the grid and the DC link voltage in the converter is regulated. The methodology of the converter control is elaborated in details and its performance on a sample faulty grid is assessed through simulation.Index Terms--Back-to-back (B2B) converter, direct-in-line wind turbine, permanent magnetic synchronous generator (PMSG), voltage drop, wind turbine control.

“…In [21], dynamical behaviour of the scalar drivers was investigated by perturbation method; moreover, bifurcation diagrams were used for verifying the chaotic responses of the system. It should be mentioned that, this method is utilised for local stability analysis of the system and cannot show chaotic phenomena in the system.…”

In this study, bifurcation and chaos phenomena in scalar drives of induction machines are investigated. Modified Poincare's map, Lyapunov exponents and bifurcation diagram are utilised for this purpose. The boundary related to bifurcated response and conditions of chaotic response is also acquired for this purpose using Poincare's map. In addition, root -locus curve of the system for stability and chaos analysis is derived by changing the controller parameters in constant speed control. In order to prove the chaotic response of the system, the largest Lyapunov's exponent is determined numerically. In addition, an experimental prototype is prepared to show these phenomena. It is shown that chaotic response of the system can be controlled by adjusting the critical values of the speed controller's gain value.
