Model Based Control System Design and Control Strategies on ETC 2008-32-0038

We are mass-producing the electronic throttle body (ETB). The nonlinearity of electronic throttle friction and the return spring Limp-Home affects the valve positioning performance of the electronic throttle control (ETC) system. The nonlinear computer ETB model was built based on mechanical and electrical design and experimental data. Two steps were used for the throttle valve controller design. The computer model was verified and designed by comparing the simulation results and the real throttle valve experimental data. A rapid prototyping processor was used for performance tests and validation of the controller and a low performance microprocessor was used for testing the implementation of the ETC, using the automatic production code generator.
