Abstract

The failure of a DC motor in an electric car caused by an error in the actuator and sensor can endanger the driver and the surrounding environment. This research focuses on the design of a Passive Fault Tolerant Control (PFTC) system that can work when an actuator and sensor error occurs in the MS150 DC modular servo system speed control. The first step is to identify the MS150 DC modular servo system. The second step is to design a state feedback control system with an integrator. The third step is to design a simulation PFTC system and design a PFTC system to be implemented in realtime. To find out the performance of the designed PFTC system, a test is carried out with a bias error of about 0.1 V to 0.8 V. On the results of implementing the PFTC system in real-time on the simulation error, the maximum overshoot value is smaller than the system without PFTC, besides the application of AFTC causes the resulting settling time is smaller than the system without PFTC.

Highlights

The use of electric cars has increased along with public awareness of the environment
Passive Fault Tolerant Control (PFTC) algorithm is applied in realtime to the MS150 DC servo
On systems without Fault-Tolerant Control (FTC), it can be seen that after experiencing an error the system response cannot return to the setpoint value and results in a steady-state error of 19.15 %

Summary

Introduction

The use of electric cars has increased along with public awareness of the environment. The main component of an electric car is a DC motor. DC motors work like a servo system with motor speed according to temporary requirements of changes in load torque. In this control system, the sensors and actuators are very sensitive and damaged [1]. PID controllers are usually used in system controls but they have poor performance when the load changes or motor dynamics [2]. The system requires control that can tolerate fault on certain limits
