Energy Management System
for Electric Engines
Using Collaborative DSP Controllers
by James W. Kirchhoff & Jacob G. Teague
Project Description
The energy management system
consists of five subsystems: a motor-generator system, a liquid
cooling system, two fixed-point 32-bit TMS320F2812 DSP control
boards, and interface electronics (shown in Figure 1).
One DSP control board will be used for engine speed control,
while the other DSP control board will be used to regulate engine
temperature. A CAN bus interface will be designed to allow
communication between the two control systems. This feature will
allow for the design of an overall control system that uses minimal
energy while providing precise temperature regulation with a fast
response to system changes such as engine speed and external load.
Advanced control algorithms such as state-feedback control as well
as artificial neural networks will be used to estimate engine power.
