“…An indirect vector control method has more advantages than other closedloop techniques for controlling RIM, such as fewer ripples in torque, the only one-speed sensor is required, and no need for air gap flux sensor [12][13][14][15][16]. Hence, an indirect vector controlled technique is used to develop a closed-loop SLIM drive [17][18][19][20]. But SLIM drive's thrust force and Velocity are varied sinusoidally and has more ripples when the end effect is considered [20].…”

An indirect matrix converter fed linear induction motor drive by considering timevarying parameters is presented in this paper. The operation and closed-loop control of the LIM is difficult due to its continuous time-varying parameters such as an air gap flux, end effect, saturation, and iron loss. Hence, the accurate mathematical model is required by considering all these effects. In this paper, the LIM is modeled by splitting the flux and current into two components, and the end and saturation effects are also considered. The indirect vector control of SLIM requires the AC to DC and DC to AC with a large capacitor. This large capacitor creates limitations such as the size of the converter increases, the life of converter decreases, and bidirectional power flow is not possible. These limitations are overcome by using direct AC to AC converter is called a matrix converter. In this paper, the indirect matrix converter is used in the indirect vector control technique in place of AC to DC and DC to AC converter. The indirect matrix converter is controlled with space vector modulation. The transient and steadystate performance of LIM, such as Thrust force, velocity, and matrix converter output voltage, input, and output currents, virtual DC link voltage, and Total Harmonics Distraction of currents are verified through using Matlab. The obtained simulation results are verified by an experimental setup with Dspace DS1104 kit.

“…to drives with superior dynamic performance. It modulates the dynamic construction of an A.C machine into that of separately excited D.C machine [15]. In D.C machine, the magnetic flux is proportional to the excitation current, if the magnetic assumed to be fixing and unbiased of armature current, the armature current affords direct torque control, then: (17) The FOC approach decouples the two additives of stator current; one imparting the airgap flux, and the other developing the torque.…”

Speed control for an I.M is a few what complex strategies; the complexity is regularly increasing in line with the required system achievement. The main forms of control strategies are scalar, direct torque, adaptive, sensorless, and vector or Field Oriented Control (FOC). The FOC method is the most efficient technique in which machine parameters: Rotor flux, unit vector, and electromagnetic torque, usually are estimated by means of using Digital Signal Processing (DSP). The Artificial Neural Network (ANN) becomes an effective tool for controlling nonlinear device in present time. This paper proposes the using of ANN instead of DSP to estimate the machine parameters in order to reduce the hardware complexity and the Electromagnetic Interference (EMI) impact. Also, it presents the PI-NN controller which is based totally on ANN. The systems simulations for both DSP and ANN are depicted. The performance of the ANN-based system gives excellent results: overshot less than 0.5%, rise time 0.514 s, steady state error less than 0.2%, settling time 0.7 s. in conjunction with that of DSPbased performance: overshot about 2%, rise time 0.64 s, steady state error less than 0.4%, settling time 0.75 s.

“…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.
