This paper presents the development of an algorithm for speed control for the induction motor using the TMS320F28069M microcontroller, the algorithms were performed based on the operating limits of the scalar control technique and the characteristics of the DSP. The control technique together with the optimization algorithm used will provide the modulations with optimization of the harmonic content, based on the method of frequency variation adopting a multi-level converter, which receives the control signals from the device's GPIOs acting as the final element control loop proposed. The adopted multilevel converter converts the voltage coming from the DC BUS to a quasi-sinusoidal AC voltage thanks to the steps outlined above, providing the power supply to the induction motor that intrinsically carries the scalar control technique.

This paper presents the speed control of a three-phase induction motor using the scalar control method with PID controller. The system maintains a constant volt to frequency ratio for any change in the load. We also used vector control method and bond graph to describe the motor model, as well as its behavior. Finally, we simulated the system using Labview, where the good results of using the scalar control technique are shown.

Sinusoidal Pulse Width Modulation

The main purpose of this work is to use a fifteenstage diode clamped multi-level inverter that is able to control the speed of an induction motor. To get reduced synchronization and high quality sine curve output voltage. The proposed plan for the diode clamped multilevel inverter is controlled using multicarrier SPWM control. An open circle speed control can be accomplished by utilizing the V/ƒ strategy. This strategy can be executed by changing the recurrence utilized in the three-stage induction motor at the stock voltage and the consistent rate. The proposed system, which results in a poor driver performance, is a useful alternative to the conventional method with high transient losses. Simulation depicts an improved drive performance by reducing the Total Harmonic Distortion resulting from the simulation and effectively controlling the motor speed.

Speed Change

This article presents the development of an algorithm for speed control of the induction motor by means of the DSP core microcontroller TMS320F28069M, which is in charge of performing the digital treatment of the voltage and current signals measured to estimate the speed of rotor and close the control loop. The algorithms consider the operating limits and the characteristics of the DSP, together with an interface that allows monitoring the estimated speed, and modifying the operating point and the constants of the PI controller, the controller output is assigned to an output of the DSP PWM_DAC which is connected to an ABB ACS800-U1 frequency converter in remote mode to carry out the motor speed change by means of a V / F control law.

Lab View

This paper gives an overview on Speed control of Induction Motor via Pic Controller using Lab VIEW. For Monitoring and controlling the Induction motor speed we can use the Lab View Simulation software. Lab VIEW Software can be used for continuous monitoring in an Real Time System applications. Most of the Industrial Automation control process are done by Lab VIEW software only. Lab VIEW Software plays major role in Industrial Monitoring and control systems. There are various types of controller used in Drive control systems in order to perform some actions such as Speed control, Run Motor in both forward and reverse direction. Here we have used Pic Controller for speed control process. From Lab VIEW software we can send Signals to Pic Controller to Run Induction Motor in either Forward/Reverse Direction and we can set the Speed of the Motor.
