“…A lot of these applications also with modifications and different demands have been made by [12][13][14][15][16] regarding the field of automation. The method of harmonic modulation has been introduced the first time in June 2011 in [17] and with a slightly difference in the control structure in [18]. Different optimization methods for the signal types used for modulation were introduced in [19].…”

“…That is a single sine signal for modulation is applied whose frequency is stated out in ω mod . The harmonic modulator can also be placed before or after the shaper (like introduced in [17]). …”

“…The 2nd order triangle signal, see also (18), is a compromise between the "ideally hist-domain" triangle signal and having only a few harmonics (ie 2, thus 2nd order) [20].…”

“…As already mentioned the 2nd order means that two different harmonics are used to build up that signal ie the first and the third harmonics. Then the question is what might be a good fitting ratio between the amplitudes of these two frequency contents should be used (see also (18)). This ratio is named " a f " and in [19] different ways of obtaining an optimum setting for a f has been analytically developed.…”

Reducing Oscillations During Positioning of A Servomechanism Having FlexibilityThis contribution describes the method of harmonic modulation of a velocity set-point signal in control to reduce undesirable oscillations. Especially the combination of this method with the well known input shaping method is of interest. Such a solution seeks for instance to a control structure used for servomechanisms equipped with a gear-box or namely mechatronic drives (MDs); where undesirable oscillations in transient- as well as semi-steady-states could arise. The combination of the methods has been proofed under real conditions in an experimental setup. Based on this, simulations regarding different industry demands and the proper choice of the modulation signal types will be introduced. Further it will be discussed which modulation signal should be used for the correspondingieindustrial demands. Both proposed methods are in the category of feed-forward-control which led to a practical implementation where no additional sensor (for measuring these undesirable effects) is needed to improve the system dynamics.

This study presents the behavioral model of thermal temperature and power generation of a thermoelectric-solar hybrid energy system exposed to dynamic transient sources. In the development of thermoelectric-solar hybrid energy system, studies have focused on the regulation of both systems separately. In practice, a separate control system affects hardware pricing. In this study, an inverse dynamic analysis shaping technique based on exponential function is applied to a solar array (SA) to stabilize output voltage before this technique is combined with a thermoelectric module (TEM). This method can be used to estimate the maximum power point of the hybrid system by initially shaping the input voltage of SA. The behavior of the overall system can be estimated by controlling the behavior of SA, such that SA can follow the output voltage of TEM as the time constant of TEM is greater than that of SA. Moreover, by employing a continuous and differentiable function, the acquired output behavior of the hybrid system can be attained. Data showing the model is obtained from current experiments with predicted values of temperature, internal resistance, and current attributes of TEM. The simulation results show that the proposed input shaper can be used to trigger the output voltage of SA to follow the TEM behavior under transient conditions.
