| Abstract: | The engine test bed was multivariate,time-varying,nonlinear and strong-coupling.The excitation current model of dynamometer was built by applying fuzzy control and PID control to excitation current control of eddy current dynamometer in the engine test bed,the fuzzy control rules were also ascertained and the control test of speed and torque was carried out with fuzzy control rules in the end.The results indicated that the fuzzy control method has high control precision,rapid dynamic response and low overshoot and can solve the problem of control stability and real-time accurate measurement for eddy current dynamometer.It is also found that the control precision may reach 4 per cent. |
