The Inflation targeting regime is a concept of monetary policy which was adopted by several countries in the 90’s; Brazil being among these countries, having adopted it in 1999 after a currency crisis. With it theoretical structure regulated by the New – Classical theory and having as its main characteristic the prior announcement of a numerical target for the inflation, this regime was adopted by countries attempting to achieve a prices stability. The present project is going to explain the theoretical basis of the regime, as well as its implementation process in Brazil and the criticism it received. However, the main focus will be on the discussion of the employment of the IPCA (Consumer Price Index) as a measuring index for Brazil’s inflation

This work aims to make the closed loop control of a three phase induction motor, through the integration of the following equipment: a frequency inverter, the actuator system; a programmable logic controller (PLC), the controller; an encoder, the velocity sensor, used as a feedback monitoring the control variable and the three-phase induction motor, the plant to be controlled. The control is performed using a Proportional - Integrative - Derivative (PID) approach. The PLC has a help instruction, which performs the auto adjustment of the controller, that instruction is used and confronted with other adjustment methods. There are several types of methods adjustments to the PID controllers, where the empirical methods are addressed in this work. The system is deployed at the Interface and Electro Electronic Control laboratory in the Universidade Estadual Paulista Júlio Mesquita Filho, Guaratinguetá, São Paulo, then, in the future, this work becomes an experiment to be conducted in the classroom, allowing undergraduate students to develop a greater affinity to the programs used by the PLC as well as studies of undergraduate and graduate works with the help of assembly made
