The AC Induction Motor (ACIM) is the workhorse of industrial and domestic applications, thanks to its simple structure and durability. Control of ACIM can be achieved by a simple open loop control technique using the conventional Volt-Hertz method. But, when dynamic responses are required, it is essential to use a closed loop control technique to reduce high current transients. The purpose of this paper is to design a closed-loop control of ACIM using the SVPWM technique and compare the performance with the conventional method. This is implemented using dsPIC for drive control, as it provides higher efficiency and lower operating costs, (i.e.) reduces the cost of drive components.Keywords: AC induction motor, SVPWM, dsPICI.INTROUTIONThe AC induction motor (ACIM ) is the workhorse of industrial and residential motor applications thanks to its simple construction and durability. These motors do not have wear-and-tear brushes or magnets that increase their cost. The rotor assembly is a simple steel cage. ACIMs are designed to operate at constant input voltage and frequency, but it is possible to effectively control an ACIM in an open-loop variable speed application if the frequency of the motor's input voltage is varied. If the motor is not mechanically overloaded, it will run at a speed approximately proportional to the input frequency. When you decrease the frequency of the control voltage, you must also decrease the amplitude proportionally. Otherwise, the motor will consume excessive current at low input frequencies. This control method is called Volts-Hertz control. In practice, a custom Volt-Hertz profile is developed that ensures correct engine operation at any speed setting. This profile can take… half the paper… evaluated in Figure 1. Coordinate Transformations Through a series of coordinate transformations, time-invariant values ​​of torque and flow can be determined and controlled indirectly with classical control loops PI. The process begins by measuring three-phase motor currents. In practice we can exploit the constraint that in a three-phase system the instantaneous sum of the three current values ​​will be zero. So by measuring only two of the three currents you can know the third. The hardware cost is reduced because only two current sensors are needed.IV. CLARK TRANSFORM Fig.2 Clark transformThe first transformation consists in passing from a 3-axis two-dimensional coordinate system referred to the motor stator to a 2-axis system also referred to the stator. The process is called the Clarke Transform, as illustrated in Figure 2.V. TRANSFORMATION PARK
