The two major criteria that we are trying to fulfill are: 1. Indeed, to effectively use this integration method with sine and cos functions would require a microcontroller with high processing power.

Other criteria that we are looking to achieve are a quick transient response quick acceleration and a response that is smooth. Gareth S Roberts 6.

The integration method used is variablestep, the Dormand-Prince method with an initial step size of 0. In this thesis, the basic concepts and equivalent circuit model of squirrel cage induction motor are explained. Gareth S Roberts 6. In this thesis, a novel field oriented control scheme for induction motor is developed. The simulation studied occurred over 2 seconds. Speed response analysis The speed response of our designed control system is the outcome that is of the utmost significance to this section of the thesis project. The displayed signals from the scopes are the basis for discussion in this section of the report. Let us say, for argument sake, that rpm is equivalent to 60 km hr-1 for our electric car. By feeding an input speed command into the system, we are going to observe the speed developed by the rotor of the induction machine over time. Both of these affect the short-term and long-term performance of the induction machine. The other curve, which resembles an over-dampened second-order control system response, is the actual speed developed by the motor. While simulation gives an excellent insight into how well the design works, it also allows the designer to witness first-hand how all the sub-systems within FO control work together to produce the desired outputs. The major conclusion that can be drawn from this graph is that our design works and there is no substantial indication of instability.Indexing document details. Field oriented control improves the dynamic performance of an induction motor and is commonly used method for speed and torque control applications. The displayed signals from the scopes are the basis for discussion in this section of the report.

Recalling that this motor control scheme would only be used to drive a hyper or electric car, it is concluded that this speed response is satisfactory. Both of these affect the short-term and long-term performance of the induction machine. The other curve, which resembles an over-dampened second-order control system response, is the actual speed developed by the motor. The integration method used is variablestep, the Dormand-Prince method with an initial step size of 0. By feeding an input speed command into the system, we are going to observe the speed developed by the rotor of the induction machine over time. A short review is presented on high voltage motor control board and DSP controllers. The Clarke's and Park's transformations are used to convert abc reference frame into dq rotating coordinate frame. To do this, we would have to add more proportional gain to the torque controller the PI controller for the speed error signal [7]. The control approach can be applied to both direct and indirect field oriented control of induction machines. This indicates the existence of high frequency components that have significant voltage magnitudes. In this thesis, a novel field oriented control scheme for induction motor is developed. Field oriented control improves the dynamic performance of an induction motor and is commonly used method for speed and torque control applications. A mathematical model is developed for squirrel cage induction motor.The problem with this speed response is that the ramp response is not very smooth; instead, it is quite coarse and jagged.
