“…The most used control strategies for IM motor are Field Oriented Control (FOC) [11][12][13][14] and Direct Torque Control (DTC) [15][16][17]. Compared to FOC, DTC provides many advantages such as (i) simple implementation (ii) absence of current controllers, (iii) quick response control, (iv) less machine parameter dependence [18,19].…”

This paper aims to improve the induction motor (IM) performance for photovoltaic (PV) water pumping systems (PVWPS) without battery storage. The proposed technique is designed by direct torque control based on fuzzy logic controller (FLC). The purpose is to ensure optimal control of flux reference to reduce motor losses and hence, the efficiency of the PVWPS is improved. The maximum power point tracking (MPPT) is achieved using a variable step size Perturb and Observe (VSS P&O) algorithm. The PV system incorporating the proposed technique is tested and compared with the control scheme based on constant flux reference under a real annual data of atmospheric conditions of the target site. The simulation results indicate the effectiveness of the proposed control strategy in terms of the reduction in stator current, optimizing flux, electrical speed and pumped water.

“…The latter is vector control based on a dynamic mathematical model of the motor [15], [16]. Vector control theories and methods mainly include adaptive control [17][18][19][20], inverse dynamics control [21][22][23], fuzzy control [24], [25], back-stepping control [26], and sliding mode control [27][28][29]. However, these energy-saving methods and measures aimed at regulating the motor speed have no significant energysaving effects, and the designs of these controllers are more complex.…”

To achieve optimal voltage regulation and energy savings of an AC induction motor operating under constanttorque and variable-working-load conditions, and consider a motor's T-type and Γ-type equivalent circuit, the copper and iron losses of the stator were regarded as invariable losses that were only related to the stator voltage, and the copper losses of the rotor were regarded as variable losses that varied with the load torque. The total electrical loss formula and the optimal voltage regulation formula for the motor were deduced. The formulas revealed that the total electrical loss of the motor was affected by the stator voltage and the rotor load torque, and the optimal voltage regulation changed exponentially with the load torque of the motor. The calculation results of an engineering example showed that when s = 0.01-0.03 and the motor operated stably, the motor load torque error was not more than 1.8 Nꞏm based on the exact and approximate solutions of the slip s. The total electrical loss showed almost no calculation error when the working voltage of the motor was higher than 230 V. The optimal voltage regulation and its error increased with the increase in the motor load torque, but within the working voltage range of the motor, the optimal voltage regulation error did not exceed 6 V. The total electrical loss with the optimal voltage regulation mode and a variable load torque was less than the total electrical loss of a 380-or 220-V constant driving mode. With the increase in the load rate, the total electrical loss increased. When the motor's load did not exceed the medium load and the motor operated with optimal voltage regulation, the energy-saving effect was significant. In particular, when the motor operated without a load, the total electrical loss was almost 0.

“…However, it requires dealing with problems related to the non-linearity in the mathematical model, which is mainly due to the internal coupling between the states variables, and the parametric variations affected by thermal and magnetic factors. Several nonlinear techniques have been developed to achieve high-performance control such as neural and fuzzy control [1,2], Backstepping techniques [3][4][5], adaptive methods [6,7], strategies based on DTC [8] and so on. On the other hand, the Sliding Mode Control (SMC) has become a very interesting method, thanks to its simplicity and its robustness against various disturbances and parametric uncertainties.…”

Induction Motors are the most used machines in the industrial field since the last century, due to their low cost, high robustness with satisfactory performance. However, they are still difficult to control compared to the DC motor because of the non-linearity presented in the mathematical model. Sliding mode theory is often used to develop powerful control against various internal and external disturbances. However, the chattering problem caused by the attractive part of the regulator is a serious problem for its applications. In this paper, the proposed solution for having an optimal performance consists in combining the Sliding Mode Control with an anti-windup proportional-integral regulator. This is achieved through a simple linear supervisor that can activate the sliding mode at start-up and transient regimes while making the second controller drive the steady state. The asymptotic stability of the delivered control signal is ensured via the Lyapunov method. This allows us to benefit from the advantages of the two regulators without having their disadvantages. This new hybrid technique can potentially offer very promising results in terms of robustness and control efficiency. The validation of this theory was carried out by simulation and then by practical implementation using a dSPACE-DS-1104 control board. The obtained results show a high-performance control with very good robustness against parametric variations and remarkable stability during all different operating zones.
