“…This justifies the recent concentration of research efforts in the design, analysis and control of the PMSM as reported in [2][3][4][5][6][7]. Recently, several efforts have been made toward the operational comparison between the permanent magnet synchronous motor and the induction motor which, hitherto, is the workhorse of the industry.…”

A fast hysteresis current-controlled (HCC) permanent magnet synchronous motor (PMSM) drive based on field orientation is presented. The objectives of this research are to develop and utilize HCC algorithm for field orientation control (FOC) of a complete closed loop speed-controlled PMSM drive system, optimize the HCC algorithm to obtain fast speed response with step and ramp speed inputs to examine the effectiveness of current and torque tracking, identify the optimal control variables of the HCC on the PMSM, examine the performance with ramp and step reference speed inputs. The response of the developed model is compared with the speed response of the standard AC6 of MATLAB Simpower systems in terms of rise time, settling time and effectiveness of current and torque tracking. Compared to the standard AC6 of MATLAB Simpower systems, the developed model achieved rise time and settling time of 0.0108 seconds and 0.0143 seconds respectively while the corresponding values for AC6 model are 0.1944 seconds and 0.1984 seconds respectively. The developed model, therefore, offered superior performance over the AC6 model in terms of rise time, settling time and tracking capability.

The reference [13] employs the mathematical model of IPMSM and attempt to linearize such a system by means of choosing the appropriate stator voltage vectors and considering bounded system uncertainties. In this case, the chattering effects are suppressed by using boundary layers, but it has produced some unacceptable steady state errors in control of torque and flux values.…”

In this paper, a novel robust direct torque controlled interior permanent magnet synchronous motor drive is presented which is based on variable structure approach and space vector modulation technique. Basically, it has similar structure as classical SVM-DTC scheme where the linear controllers are replaced with sliding mode type of controllers. In this case, the chattering effect has been addressed by using PI controllers within the specified boundary layers of switching surfaces. Such a combination of sliding mode controller and PI controller has been employed for controlling over stator flux, electromagnetic torque and rotor speed in the proposed direct torque control scheme. In fact, the SMC is in charge of transient response control and PI controller prevails in the steady state. As a result, the lack of robustness in linear controllers is compensated by SMC while the chattering effects and steady state errors of such sliding mode controllers are suppressed by smooth control obtained through PI controllers. The drive performance improvements are also investigated through the presented comparative simulation studies.Keywords-direct torque control, permanent magnet synchronous machine, robust control, variable structure.
