Abstract: This paper proposes a velocity control approach for the light electric bike with human power assistance. The velocity control signal is composed of two signals. One is a velocity-dependent equilibratory torque to compensate the wind resistance. Another is a deviation torque to achieve desired multi-objective performance represented in terms of linear matrix inequality (LMI) conditions. The formulated multi-objective performances includes the invariant set of state variable under the magnitude bounded disturbance, the magnitude bound on the regulated output, and the performance optimization for attenuation of various disturbance effects on the regulated output. The disturbances include the deviations of tire resistance, human assistant torque, and driver¡¦s weight from nominal values. Based on the parameters and specifications of the EL-168 electric bike produced by KENTFA Advanced Technology, Taiwan, the design results are verified through time-response simulatio!
ns under both the flat and linear varying gradient road conditions.
