Response Modeling

The idea orients to develop a PI controller for closed loop speed control of chopper fed dc drive. PI controller is one of the most preferred controller for speed control of dc drive, which can be easily understood and implemented in practice. The speed of the chopper fed separately excited dc motor can be regulated from below and upto rated speed by using a chopper as a converter. The signal corresponding to the speed error of the motor and change in speed error are given as inputs to the PI controller. The controller output provides the required gating signal that is used to vary the duty cycle of chopper. The chopper firing circuit receives signal from controller, gives variable voltage to the armature of the motor for achieving desired speed response. Modeling of chopper fed dc motor is done. Two loop control system is designed, one for current and another for speed. The complete model of proposed system is simulated using MATLAB (SIMULINK). Also the performance of the simulated model is investigated by using various controller tuning methods.

Fuel Consumption And Emissions

In order to reduce the fuel consumption and emissions of automobile, the engine idle speed control method was studied. The basic concept of engine idle speed and the requirements and strategies of idle speed control were introduced, and the features and structures of CAN bus technology were analyzed. An idle speed control system of automobile engine based on CAN bus was designed which included main control module, front control module and rear control module. The overall structure, hardware design and software implementation of the system were given. The system can realize the desired functions, and it has certain application value.
