Abstract. This paper use the digital signal processor (DSP) TMS320LF2407A control chip is adopted as core of the control system. Three closed loop of the controller, namely electricity, speed and displacement, were designed. Using space voltage vector pulse wide modulation technology (SVPWM), constructed a servo system of permanent magnet synchronous motor(PMSM) based on DSP. Through debugging ...

This paper presents the development of an embedded motion controller for a voice-coil driven linear motion stage. The linear motion module is integrated with a voice coil actuator, a linear guidance system, and a linear encoder. The controller is based on a TI TMS320LF2407A DSP board. It performs the servo motion control by providing motion profile generation, position determination, position e...

A Microcontroller based digital pH meter was designed and developed to measure the value of pH (acidity or alkalinity) for any type of solution. Two op-amps of high input impedance and low output impedance were used to design the pH meter: one is used as a buffer and the other as a summing amplifier. The output of the summing amplifier is connected to the microcontroller as an input. The pH val...

In this paper, a hardware in the loop simulation (HIL) is presented. This application is purposed as the first step before a real implementation of a Generalized Predictive Control (GPC) on a micro-grid system located at the Military University Campus in Cajica, Colombia. The designed GPC, looks for keep the battery bank State of Charge (SOC) over the 70% and under the 90%, what ensures the bes...

In this paper the method of sensorless startup of direct current brushless motor using third harmonic back Electromotive Force (EMF) and motor startup using microcontroller for pulse width modulation, power switch control and motor output analysis is presented which renders RPM control and high speed achievement for motor. The microcontroller is used for processor and MOSFETs are used for power...

Microcontrollers are very popular in electronics and computer-controlled systems worldwide. This paper presents the control of a microcontroller-based system using the computer and explains comprehensively the hardware and software parts of the microcontroller. Peripheral Interface Controller (PIC) software developed by Microchip (MPASM) is used in programming a PIC microcontroller, and Visual ...
