Jun 21, 2017 · Voltage PWM is used to force maximum current into the machine to maintain the desired torque level. The block diagram for the general closed‐loop speed and current control of the SRM is shown in Figure 5. In speed control applications, an outer speed loop is added to the faster inner current loop.

Figure 1 illustrates the basic block diagram of switched reluctance motor which essentially consists of a source for excitation, converter for phase switching of coils, sensing unit for position sensing and a controller to control the parameters and to …

Switched reluctance motor works based on the variable reluctance principle. The rotating magnetic field is created with the help of power electronics switching circuit. The main concept is the reluctance of the magnetic circuit is depending upon the air gap.

Figure 1 shows the block diagram of a closed loop speed control of SRM drive system. The controller has two loops. ... ... to the SRM control scheme without torque control...

Closed-loop speed and current control block diagram of a SRM. The effective performance characteristics from a SRM drive system can be obtained by proper positioning of the phase excitation pulses relative to the rotor position.

Feb 28, 2025 · Using MATLAB/SIMULINK Software, an 8/6 4-phase SRM is simulated using the proposed converter and controller, the controller here is a closed loop control of voltage PWM SRM drive with an inner current loop. The simulation data validated the torque ripple-reducing capability of the suggested converter in the SRM control process.

An outer speed PI control loop in the induction motor drive, shown in Figure computes the frequency and voltage set points for the inverter and the converter respectively.

The effectiveness of closed loop and open loop systems are contrasted. Additionally, the suggested converter for the SRMT is assessed in loaded conditions, and a comparison of the no-load and loaded SRM is shown.
