“…So the M/T method which is combination of M and T methods is proposed. This method measures not only encoder pulses but also clock pulses at a constant detecting time so that it combines the advantages of M and T methods with high accuracy in wide speed range [4][5][6]. When the number of encoder pulses is marked as m1, while the clock pulses is m2 and system sampling period is called Ts, as shown in Figure 1.…”

Abstract. In this paper, a new M/T method of variable sampling period is introduced for speed measurements by optical incremental encoders. In this method, we estimated the number of encoder pulses to count in next counting interval at the end of every sample period, so the sampling intervals were variable. Both encoder pulse and high frequency clock pulse were counted in the variable intervals and the counting of clock pulses begins and ends at the exact rising age of the encoder pulse. Through this method, the error is only one clock pulse which is much shorter than encoder pulse, which guarantees a more accurate speed measurement and rapid response of motor system.

“…As a result, direct differentiation is not used in industry. Instead, to measure the speed of a mechanical system, the M/T method [23] and/or a Luenberger observer are adopted. If an encoder is installed, the M/T method can be utilized, and it shows reasonable performance in terms of speed estimation.…”

A method for the identification of mechanical parameters based on integral calculation is presented. Both the moment of inertia and the friction constant are identified by the method developed here, which is based on well-known mechanical differential equations. The mechanical system under test is excited according to a pre-determined low-frequency sinusoidal motion, minimizing the distortion, and increasing the accuracy of the results. The parameters are identified using integral calculation, increasing the robustness of the results against measurement noise. Experimental data are supported by simulation, confirming the effectiveness of the proposed technique. The performance improvements shown here are of use in the design of speed and position controllers and observers. Owing to its simplicity, this method can be readily applied to commercial inverter products.

“…The variables, in this method, are: the number of encoder pluses (m) and the duration of these pluses (T). There are distinctly three methodologies found in [2]. These are (i) the m-method, (ii) the T-method and (iii) the method.…”
