Optimalisasi Kontrol Pedelec Pada Mobile Cafe Hybrid Dengan Efisiensi Beban Torsi Berbasis Sensor Torsi
This research aims to optimize the pedelec control system on a hybrid mobile cafe by using a torque sensor as a PI control parameter. The Hybrid Mobile Cafe is a bicycle that combines the rider's pedaling with the assistance of a DC electric motor for additional power. The main problem faced is uphill road conditions that can affect the rider's performance. The implementation of the Bottom Bracket Torque Sensor T-17 on the Hybrid Mobile Cafe allows riders to ride on uphill terrain. By applying a PI control system with input from the torque sensor, the Hybrid Mobile Cafe can receive an adaptive electric motor response to changes in torque load from the rider. The Bottom Bracket Torque Sensor T-17 can measure rider torque from a range of 0-588.8 so that rider torque on slopes of more than 10 degrees can still be detected. On an 8-degree road slope with gear variations of 1-10, the test results show that gear 1 produces an average torque of 37.93 Nm, and the torque value continues to increase until gear 10 which reaches an average of 75.55 Nm. On a 4-degree road slope with gear variations of 1-10, the test results show that gear 1 produces an average torque of 24.45 Nm, and the torque value continues to increase until gear 10 which reaches an average of 54.20 Nm. The implementation of the PI control system based on the rider's torque parameters. with a 4-degree slope and using the values of Kp = 1.75 and Ki = 0.42, assistance from the motor can reduce the torque of the Hybrid Mobile Cafe rider with a travel time of 1 minute 22 seconds.
