The river has become an inseparable part of human life, but river water's excessive overflowing can lead to disaster, namely flooding. Floods are quite common globally, but the people are often not ready to deal with it as there is no early warning to the public about the upcoming flood. The development of a smart monitoring city or referred to as SMOORTY in this study was made to provide a warning of the possibility of a flood disaster. SMOORTY application can help as one solution to improve the community's alertness in dealing with floods by providing an early warning notification through WhatsApp. SMOORTY also provides reports to monitor the river water level. SMOORTY uses a Raspberry Pi microcomputer to run the system and is supported by an ultrasonic sensor to measure the distance between SMOORTY and the measured river water. SMOORTY also has a warning system implanted in the device in the form of a buzzer and an LED that will be active when the water level exceeds the threshold limit. Keywords— Flood, Monitoring, Warning, Raspberry Pi, Water Level Sensor.

Indirect field-oriented control (IFOC) of a linear induction motor (LIM) drive is an important challenge because of the end effect and nonlinear behavior of the LIM drive. It becomes more complex in high-speed applications and flux-weakening (FW) regions when current and voltage constraints must be satisfied. Moreover, considering the primary resistance in voltage constraint inequality makes the calculations even more complicated.This work presents a new FW control algorithm for LIM drives, considering the end effect and the primary resistance. Consequently, the reference d-axis current and maximum q-axis current are modified considering the primary resistance and end effect. Accordingly, new control strategies for the partial and full FW regions are implemented in a LIM drive. Fuzzy logic controller (FLC) has been used to overcome the nonlinear behavior of LIM drive and achieve appropriate dynamic characteristics. Simulation results validate the effectiveness of the suggested LIM drive based on FLC in different speed regions. Moreover, results manifest that in a LIM drive with end effect consideration, the base and the critical speeds are not constant. As the LIM speed increases, the base frequency reduces, whereas the critical frequency increases.

“…Among all of these research achievements, fault estimation and compensation based on disturbance observer (DOB) has attracted a lot of attentions benefit from more degrees of control freedom, high implementability in real-time, etc. A generalized DOB family defined by Chen et al [17] contains linear and nonlinear DOB, equivalent input disturbance, extended state observer (ESO), generalized proportional integral observer (GPIO) [18,19], extended high-gain state observer and so forth. Almost all of these DOB methods can provide information of multi-state estimation, which plays an important role in disturbance attenuation.…”

An Active FTC Strategy Using Generalized Proportional Integral Observers Applied to Five-Phase PMSG based Tidal Current Energy Conversion Systems

et al. 2020

In recent years, multi-phase permanent magnet synchronous generators (PMSGs) have become attractive in the field of tidal current energy conversion systems (TCECS) due to their high-power density, reliability, and availability. However, external disturbances and malfunctions in power conversion chains will bring challenges to achieving stable and continuous tidal current energy harnessing. Using generalized proportional integral observers, an active fault-tolerant control (AFTC) strategy is therefore proposed for a five-phase PMSG based TCECS that is subjected to an open switch fault (OSF) in the generator side converter. This proposed AFTC strategy is applied into q-axis current control loops, which contain fault detection and compensation. The fault compensator will be smoothly activated using a sigmoid function once the OSF is detected. Finally, a small-scale power experimental platform emulating the TCECS is established in order to verify the feasibility and efficiency of the proposed FTC strategy. Experiment results show that this AFTC strategy can detect faults rapidly and effectively attenuate torque ripples in the post-fault operation mode.
