Generally, friction/disturbance compensation is an important issue in high-precision motion control applications. In particular, when the system under control undergoes low-speed or reversal motions, the friction force and external disturbances will degrade motion accuracy. Therefore, to achieve satisfactory motion performance, it is necessary to simultaneously compensate for the friction force and...
Recently, interior permanent magnet synchronous motor (IPMSM) drives are getting more popular in many applications such as electrical vehicles. In order to achieve maximum torque per ampere (MTPA), knowledge of the motor parameters is necessary. Due to the saturation effect, variation of the motor parameters such as inductances is not avoidable. The main contribution of this paper is to use the well...
This paper presents a sensorless predictive torque control. The predictive torque control is based on pre-calculation of the best switching state in order to keep the state variables close to desired values. The control scheme uses a proportional-integral controller inside of predictive control in order to improve the steady state response. The stator flux that determines the stator voltage is pre-calculated...
This paper presents and discuses different PI tuning methods and control strategies for a permanent magnet synchronous machine. The machine is a part of a wind turbine generation system in which two back-to-back-connected three-level converters are the power interface to the electrical grid. It is demonstrated that, for the speed control loop, the zero-pole cancellation method does not provide good...
In this paper, we studied the vector control with orientation of rotor-flux by using PI regulators for an induction machine without speed sensor, and with adaptation of the rotor resistance. The rotor speed is estimated by using the model reference adaptive system approach (MRAS). This method consists of using two models. The first one is the reference model and the second is an adjustable one in...
This paper presents hybrid PI (HBPI) controller of IPMSM drive using fuzzy adaptive mechanism control. In general, PI controller in computer numerically controlled machine process fixed gain. They may perform well under some operating conditions, but not all. To increase the robustness, fixed gain PI controller. HBPI controller proposes a new method based self tuning PI controller. HBPI controller...
