“…The control function of the PI controller is given in Equation 20, while its synoptic diagram is shown in Figure 10, where e(t) is the error, and K p and K i are respectively the proportional and integral coefficient terms. Although the PI controller is commonly used in a wide range of applications, several drawbacks such as the difficulties of finding out the constants K p and K i are causing a big issue [67][68][69][70]. Moreover, its sensibility dealing with the load variations has caused researchers to look for another controllers that can provide robustness against load variations.…”

A Robust Maximum Power Point Tracking Control Method for a PEM Fuel Cell Power System

Taking into account the limited capability of proton exchange membrane fuel cells (PEMFCs) to produce energy, it is mandatory to provide solutions, in which an efficient power produced by PEMFCs can be attained. The maximum power point tracker (MPPT) plays a considerable role in the performance improvement of the PEMFCs. Conventional MPPT algorithms showed good performances due to their simplicity and easy implementation. However, oscillations around the maximum power point and inefficiency in the case of rapid change in operating conditions are their main drawbacks. To this end, a new MPPT scheme based on a current reference estimator is presented. The main goal of this work is to keep the PEMFCs functioning at an efficient power point. This goal is achieved using the backstepping technique, which drives the DC–DC boost converter inserted between the PEMFC and the load. The stability of the proposed algorithm is demonstrated by means of Lyapunov analysis. To verify the ability of the proposed method, an extensive simulation test is executed in a Matlab–Simulink T M environment. Compared with the well-known proportional–integral (PI) controller, results indicate that the proposed backstepping technique offers rapid and adequate converging to the operating power point.

“…Electro-magnetic force defines one major characteristic of a motor and is closely related to motor noise and vibration; it has been actively analyzed [ 1 , 2 , 3 , 4 , 5 ]. Any periodic function can be represented as the sum of harmonic functions of multiples of fundamental frequency [ 16 ].…”

“…Contrary to the size and simplicity of these motors in terms of structural design, sources of motor noise and vibration are often complicated, tracing back to electro-magnetic forces between armature and permanent magnets or the switching of brushes, housing resonances, bearings, etc., which are quite diverse. Electro-magnetic force and cogging torque are major characteristics of such motors, and these aspects have been actively analyzed [ 1 , 2 , 3 ]. Measurement and analytical work related to motor noise sources is relatively few, possibly due to the diversity of motor types and complexity of noise sources.…”

Small direct current (DC) motors are widely used due to their low cost and compact structure. Small DC motors of various designs are available on the market in different sizes. The smaller the motor, the more closely it may be used by individuals. Contrary to the size and simplicity of these motors in terms of structural design, sources of motor noise and vibration can be quite diverse and complicated. In this study, the source of motor noise and vibration was visualized over a very wide range of frequencies. The particle velocity of the motor was reconstructed from nearfield sound pressure measurements of motor noise. In addition to noncontact measurements conducted on a motor running at constant speed, the particle velocity of a stationary motor due to the impulse of an impact hammer was measured with an accelerometer. Furthermore, motor noise was measured under motor run-up conditions with different rotational speeds. As a result, by combination of these three methods, the sources of motor noise were accurately identified over a wide range of frequencies.

“…The market of PMSM-drive systems is growing because of low cost and high reliability. These drive systems have conventional utillizations for fast dynamic position drives and machine manipulation shaft drives, due to their torque-to-losses ratios, the effects of ripple in torque that decay the machine lifespan and position path especially at high-speeds, the noises and losses are increased [8]. In [9], a dead time compensation strategy has been proposed to mitigate the motor torque ripple for an 80 kW PMSM.…”

AC-drive systems based Permanent Magnet Synchronous Motor (PMSM) are widely utilized in industrial applications due to many advantages including excellent efficiency, best reliability, and low-effective cost compared with DC-drive systems. Design and implementation of an RLC compensator for a PMSM-drive system is demonstrated in this paper. The main aims of using an RLC compensator are decreasing of Total-Harmonics-Distortion (THD) of the input line current and Ripple Factor (RF) of the electromagnetic torque over a wide range variation in rotor speed and load. The entire transfer function of the proposed system is derived for stability verification under the change of rotor speeds. The proposed PMSM-drive system is implemented with and without RLC compensator for two cases; which are at a fixed load and a step-change in load. Good performance is achieved using the proposed RLC compensator; in terms of THD and RF are 0.77% and 3.13%, respectively.
