“…Hysteresis controller is one of the most preferred technique used for all the applications of current controlled and voltage source inverters. It exhibit very good dynamical properties as well as robustness, property of inherent peak current limiting and simple hardware implementation makes it most popular [10] [11]. The bandwidth of the hysteresis current controller computed by comparing the load current with the reference current using hysteresis comparators as shown in fig.1 By varying in the inverter operating frequency current waveform can be compensated.…”

“…From the definition of the Lyapunov function or energy Function if in each state it is possible to find out a control law to reduce the energy of the system, it is possible to bring the energy of the system to zero, i.e., to bring the system to a stop which means the stable condition of the system.

During the last few decades, intense research on the detection of crack using the vibration based techniques has been done and various approaches have been developed by researchers. In the present paper, detection of the crack presence on the surface of composite cantilever beam-type structural element using natural frequency is presented. First three natural frequencies of the cracked beam have been obtained experimentally and used for detection of crack location and size. Detected crack locations and size are compared with the actual results and found to be in good agreement. Also, the effect of the crack location and the crack depth on the natural frequency is presented. Experimental Modal Analysis (EMA) was performed on beams with cracks and the measuring first three natural frequencies changes. To identify the crack, contour of each normalized frequency in terms of the normalized crack depth and location are plotted. The point of intersection of three curves gives crack location & depth. It is observed that, results obtained from experimental method have a very good agreement with actual results also we can justify the results through simulation.

“…Among these current controllers, the hysteresis band (HB) current controller features inherent current limiting capability, robustness, no modulation stage and simple implementation, in addition to the excellent dynamic and tracking performance [4]. The HB controller has been mainly used in the VSI, and active research on this includes constant switching frequency control [5], online computation of bands [6] and multi‐band hysteresis control [7, 8]. In [9], a comparative study of fixed‐band and sinusoidal‐band hysteresis current controllers (F‐HB and S‐HB) was carried out for VSIs; however, HBs are impractical and the comparison needs further evaluation for various bandwidths and sampling frequencies.…”

The hysteresis band controller offers excellent dynamic performance. It has been widely researched and applied for the voltage source inverter and inverter fed drives, however it has not been investigated within the context of a matrix converter or a matrix converter based motor drive. In this paper, both fixed-band and sinusoidal-band hysteresis current controllers are proposed and developed for a direct matrix converter. A comprehensive comparative evaluation of the two methods is then carried out. Both methods have fast dynamic performance and they inherently integrate the line modulation technique of the virtual rectifier stage into the overall modulation. Surge currents are prevented with the proposed scheme. The sinusoidal-band hysteresis controller demonstrates lower total harmonic distortion at the expense of higher average switching frequency, which is only significantly observable at very high sampling frequencies. The proposed controller is integrated with the field-oriented control to drive a matrix converter fed permanent magnet synchronous machine. The proposed methods are simple and incur a light computational burden, which advances the practical applications of matrix converters in AC motor drives. The simulation and experiment results demonstrate the effectiveness and feasibility of the proposed scheme.

The HB control has been constrained to the VSI and active research on this includes constant switching frequency control [4], online computation of bands [5], and multi-band hysteresis control [6]. For a high inertia system that requires dynamic braking, the VSI based drive system usually requires a rectifier stage to supply the DC voltage and the braking chopper to absorb the kinetic energy generated from the motor deceleration as shown in Fig.…”

This paper presents work on the hysteresis band control for output current regulation in a direct matrix converter in order to drive an induction motor. The hysteresis band controller offers excellent dynamic performance. It has been extensively researched for the voltage source inverter and inverter based drive systems, but it has not been investigated within the context of a matrix converter or a matrix converter based motor drive. Firstly, this paper proposes a fixed-band hysteresis current controller for a matrix converter to track the prescribed current references, and then a sinusoidal-band hysteresis current controller is proposed. Both methods have fast dynamic performance and they inherently integrate the line modulation technique of the virtual rectifier stage into the overall modulation. The extra modulation stage is not required and the surge current is inherently prevented. The sinusoidal-band hysteresis controller demonstrates that it generates lower harmonic content at the expense of the higher average switching frequency. Following this, both methods are tested as a drive for an induction motor with field-oriented control. With the matrixconverter-based drive system, one significant benefit is that the braking chopper is removed due to the bidirectional feature. The methods are simple and have light computation burden. The obtained results demonstrate the effectiveness and feasibility of the proposed scheme. The experimental work is being carried out to support the proposed scheme.
