Abstract: An approach of hardware
in-the-loop simulation(HILS) and optimization based on Windows is adopted to
develop and optimize the algorithms in the supervisor and control system of
dynamometer test bed.The HILS scheme of test bed is designed.The constitution
of the measurement and control system is introduced.The dynamic data
exchange(DDE) between configuration software and simulation software MATLAB
based on Windows is discussed.The identification model of Engine and eddy
current dynamometer system is acquired.Finally,the application of HILS approach
in the eddy current dynamometer test bed and the PID control algorithm
optimization is given.
Keywords: HILS;Configuration Software;Eddy
Current Dynamometer;
MATLAB;Parameter Optimization
