Optimal Control of All-Electric Dual-Belt CVT Speed Ratio Based on IGSA-PID
Dual-belt Electro-Mechanical Continuously Variable Transmission(DEM-CVT)uses DC motor to adjust the work-ing radius of driving wheel and driven wheels,which can be realize speed ratio change adjustment.It has two groups of belt trans-mission devices which can effectively improve the carrying capacity of CVT.DEM-CVT has two operating modes:single-band and double-band.By designing mode switching strategy based on optimal efficiency,it can effectively improve fuel economy.Aiming at DEM-CVT speed ratio control,this paper designs a speed ratio control strategy for different working conditions and a speed ratio control method based on IGSA-PID.Through modelling and simulation,the effectiveness of the proposed speed ratio control strategy and control method are verified.
