State Estimation in Induction Motors by Using Taylor Series Approximation
Saadettin Aksoy1 and Hakan Kızmaz2
Abstract. Field-oriented control techniques can be classified as indirect or feed
forward method. In the first case, the coordinate transformation is obtained via the slip speed
which is indirectly determined using some parameters. In the second case, the flux
components, which are determined by an observer, are used to obtain the mentioned
transformation [1], [2]. Consequently, estimation of the rotor flux components from terminal
variables such as stator voltage current and rotor angular speed has been a major task in the
theory and practice of the field-oriented control of the induction motors [1]-[5]. HYPERLINK \l
"LIJ05" However, the rotor flux cannot be directly measured in squirrel-cage induction
motors. Therefore, it is required an estimator or state observer to provide the rotor flux. The
Taylor series are defined on the interval t [0,1] and have the orthogonality property like the
Walsh, Chebyshev and Legendre series [6]-[8]. The proposed algorithm uses some important
properties such as the operational matrix of integration for Taylor vector [9].
In this paper, a simple algorithm that uses input-output measurements such as stator
voltage, current and rotor angular speed for the simultaneous estimation of the rotor flux
components of induction motors is presented. The proposed algorithm, which is simple in
form and convenient for computer usage is based on Orthogonal Taylor Series Approximation
and consists of three steps. In the first step, the feedback gain matrix G is a function of speed
and it should be determined for each different speed measurement values. In the second step,
stator voltage and current measurements and unknown state vector are expressed in a Taylor
series. Thus, we approximate the continuous-time functions with Taylor functions. Finally, in
the last step, the observer state equations are converted into integral equations by integrating
the terms on either side of the equations. After some algebraic manipulations, state observer
equation is transformed into a computationally convenient algebraic form whose solution can
be obtained easily by a computer program. Consequently, resulting this recursive solution
unknown state vector is easily calculated. The proposed algorithm has been implemented in
MATLAB and it has been applied to a squirrel-cage induction motor which was fed from
various supply sources such as sinusoidal, six-steps and PWM waveforms at different

operation conditions. Results obtained by proposed algorithm are in harmony with the real
results.
