| Summary: | The use of Permanent Magnet Synchronous Motor, or PMSM has increased rapidly
in recent years, mainly in electric vehicles where it is used as the main drive motor
due to its several advantages. In electric vehicle systems, one of the strategies to
optimize the performance of electric cars is to design an efficient motor speed
control. Designing an efficient motor speed control can affect a number of factors,
such as the efficiency of converting electrical energy into motion, vehicle speed,
and battery durability. Many ways are pursued for this energy efficiency, including
through setting the optimal speed control of the motor in an electric vehicle. In this
research, a PMSM motor speed control system with minimal control signal energy
is made. The optimal control system scheme is made with a linear quadratic
performance index, or Linear Quadratic Integrator (LQI). PI controller is used as
a comparison. It is desirable that the created LQI controller satisfies the required
response specifications. In realizing the torque control method, Field Oriented
Control (FOC) is used in this paper. To validate the effectiveness of the proposed
method, simulation and implementation have been performed using Texas
Instrument's Motor Control Kit hardware model which consists of: Launchpad
F28069M microcontroller, Boostxl 8305-evm motor driver, and Teknic 2310P
dual-motor (PMSM) connected to Simulink Matlab. Experimental results have
confirmed that the LQI technique can offer minimum control signal energy
performance and satisfy the required response specifications. |
