Model based design to control DC motor for pedal assist bicycle

The contemporary types of pedal assist bicycles such as throttle and cadence based demands user effort in order to achieve the desired speed. However, the control mechanism defined in the existing techniques could not sufficiently bolster the user´s usability and reliability. This paper defines a novel control mechanism where the user possesses ideal control over the controller to manipulate the desired speed obviating much physical endurance. This control has been achieved by creating a co-simulation platform between two software tools namely Amesim and MATLAB. The dynamic model of a bicycle was built using Amesim, the control strategy was developed using MATLAB and the data exchange was realized through Amesim special interface module and MATLAB S function. The performance simulation was performed on the co-simulation platform, and the simulation results show that by using a co-simulation platform, the desired speed can be achieved with much accuracy irrespective of the terrain.
