“…Since most methods require the knowledge of machine parameters, many research efforts are focused on robust control that not depends on parameter variations of induction machines. In [2] a new stator current sensorless position-flux tracking control algorithm, which is robust to electrical motor parameter variations, is presented. The salient advantage of the observer [3] is that it does not need the information of any machine parameter.…”

In this paper the steady state characteristics of a self tuned field oriented control induction motor drive are presented. The induction motor will be self tuning after one or more of its parameters varied. Both basic types of field oriented control have some sensitivity to machine parameters and provide non-ideal torque control characteristics when control parameters differ from actual machine parameters. In general, both steady state torque control and dynamic response differ from the ideal instantaneous torque control achieved by a correctly tuned controller.

“…The estimation of the current without using a DC-link current sensor is presented in [21,[24][25][26][27][28][29][30][31]. These methods use either a speed encoder/voltage sensor/single-phase current measurement and an accurate machine model to estimate the currents.…”

Performance of a Vector-Controlled PMSM Drive without Using Current Sensors

The current sensorless vector-controlled permanent-magnet synchronous motor (PMSM) drive using a single sensor (i.e., speed sensor) is presented in this work. The current sensors are removed, and the estimated currents are used to close the current loop to minimize the drive cost and make it fault-tolerant against current sensor failure. A classical vector-control PMSM drive requires at least three sensors, i.e., two current sensors and one speed/position sensor. This paper presents a new current estimation technique that is free from inverter switching states, an integrator, and differentiator terms. The drive is suitable for retrofit applications, as it does not require any additional hardware. The reference voltages (vds and vqs) are used to estimate the rotor reference frame currents (i.e., iqs and ids). The presented algorithm depends on the stator resistance (Ɍs). The online Ɍs estimation algorithm is used for compensation to overcome the effect of the Ɍs on the estimated currents. The sensitivity analysis for the currents against the speed is verified and presented. The speed loop is closed with actual speed information, which will try to maintain the reference speed under any circumstances. The proposed current sensorless PMSM drive was validated using MATLAB/Simulink and also verified on a hardware prototype. The presented technique was verified for various operation conditions, and some of the extensive results are presented.

“…It is noticed that all of the aforesaid methods based on DC-link current measurement require the information of machine model and switching states of the inverter. In [14][15][16][17][18][19][20][21][22], current sensorless algorithms are presented. All these methods are based on accurate machine models, which weaken the robustness of the corresponding drive.…”

This paper presents a current sensorless vector controlled induction motor drive with only speed sensor present in the system. The same performance as that of normal vector control drives (which uses two current and one speed sensor) is achieved with the proposed current sensorless drive. Such an approach is suitable for applications, where speed sensor cannot be eliminated. Thus, elimination of current sensor results in reduction of cost, increases reliability, reduced size and noise immunity. A new current estimation algorithm is proposed in this paper. The current estimation algorithm, estimates the current in two phase stationary reference frame. The proposed current estimation technique can also be used as a fault tolerant algorithm for normal vector controlled drives in case of current sensor failures. The performance of the current sensorless drive using the proposed current estimation technique is verified through MATLAB/SIMULINK. Extensive simulation results are presented to confirm the effectiveness of the algorithm. The algorithm is also experimentally validated with the laboratory developed prototype and the results are presented. The prototype is built around a dSPACE 1104 controller board.
