“…Harnefors and Nee [8] introduce a position and speed observer-based estimator for AC motors, using electric variables measurements. In [9] mechanical variables are estimated from electrical ones in a brushless DC motor. In [10] a nonlinear reduced order observer is used for estimating mechanical variables in a permanent magnet synchronous motor.…”

This work deals with speed estimation in electric drives that include a Permanent Magnet Stepper Motor. On the one hand a nonlinear observer is designed, whereas on the other hand the rotor speed is estimated by using the dirty derivative from the measured position. By assuming model uncertainty and noisy measurements a comparison from the robustness point of view is presented. Advantages and disadvantages of both techniques are commented.

“…The second group is based on estimation techniques that usually utilize phase voltages and currents of the motor. By using these quantities, the rotor position of the motor can be determined using a state observer [4]- [6], or a Kalman filtering technique [7], [8], or by direct calculations [9]- [11]. However, these techniques are computationally intensive, and large rotor position detection errors may occur because of quantization and truncation errors, and measurement inaccuracies.…”

Abstract-This paper proposes and implements a novel rotor position sensorless technique for PM ac motor drives, which allows acceleration from standstill and can operate under various practical operating conditions including transient speed changes. The technique developed here relies on the measurement of the phase voltages and currents of the motor. It uses the incremental values of flux linkage, and the back-EMF functions to estimate incremental rotor position. Using a phase-locked loop (PLL) algorithm, an internal closed-loop correction algorithm can correct rotor position estimation drift, which may be due to the motor parameter variations or measurement inaccuracies. The method is implemented in closed-loop using a digital signal processor (DSP), and details of the implementation are provided in the paper. To demonstrate accuracy, robustness and reliability of the position estimation scheme, the paper presents a number of real-time experimental results, including dynamic operating conditions.
