“…This control is particularly suitable for hypercar applications, because it is robust with respect to temperature and voltage variations typical of battery voltage variations depending on the State of Charge and absorbed current and motor temperature variations under frequent and strong overload operations. Figure 10 also includes the contribution of the feedforward responsible for compensating the disturbances and improving the dynamic performance [26]. The FOC 4D requires the implementation of 4D-LUTs with a significant amount of computational resources involved, as each LUT needs to be populated with data for all possible combinations of torque, speed, voltage, and temperature.…”

Nowadays, electric vehicles have gained significant attention as a promising solution to the environmental concerns associated with traditional combustion engine vehicles. With the increasing demand for high-performance hypercars, the need for advanced torque control strategies has become paramount. Field-Oriented Control using Current Vector Control represents a consolidated solution to implement torque control. However, this kind of control must take into account the DC link voltage variation and the variation of motor parameters depending on the magnets’ temperature while providing the maximum torque production for specific inverter current and voltage limitations. Multidimensional lookup tables are needed to provide a robust torque control from zero speed up to maximum speed under deep flux-weakening operation. Therefore, this article aims to explore the application of FOC 4D control in electrical hypercars and its impact on enhancing their overall performance and control stability. The article will delve into the principles underlying FOC 4D control and its advantages, challenges, and potential solutions to optimize the operation of electric hypercars. An electric powertrain model has been developed in the Simulink environment with the Simscape tool using a S-function block for the implementation of digital control in C-code. High-power electric motor electromagnetic parameters, derived from a Finite Element Method magnetic model, have been used in the simulation. The 4D LUTs have been computed from the motor flux maps and implemented in C-code in the S-function. The choice of FOC 4D control has been validated in the main load points of a hypercar application and compared to the conventional FOC. The final part of the research underlines the benefits of the FOC 4D on reliability, critical in motorsport applications.

“…What we want is an initial period of 0.5 second for starting time and an end period of 0.75 second stops time in the controlled position as Figure 1 shows. The control system for servo motors is corrected at any time if there is a surplus or shortage of controlled position [1], [2]. This problem is very disturbing in making other control systems because if the time used is long enough in the process of starting time and stopping time, this process will repeat at any time according to the modulation of the control code received by the transistor igniting system, while the desired system operating time is only 30 seconds, such as its use on high-velocity tools above 2 much or 2×300 m/s, starting from start to stop at the end of the process, in controlling the direction of motion on high-velocity equipment to chase objects that are also high-velocity.…”

The background of research try to use an open loop system, without feedback, by building torque in the target position. Theoretical basis manages the turning round of servo motor change direct currents to alternating currents by adjusting the rate input used. Methodology in simple terms, the flowchart of code processing from igniting transistors to managing the turning round of a three-phase alternating current (AC) servo motor. The result of the transistor ignition time with room phasor pulse width modulation (PWM) to set the ignition of a three-phase AC servo motor in the process of igniting as ordered, for manage position only igniting transistors in target position, and building torque at there. Discussion, igniting transistors to manage the turning round of servo motors, allows motion of servo motor, allows motion of servo motor to be added faster, accurately, soft, and steady. In conclusion, in this case the researcher uses it more specifically by turning on the transistor only at the target position, so that the torque generated is only at the target position, the servo motor motion from the start position immediately ends at the target position. Suggestions, this system igniting can be applied at a motion high-velocity system like a missile system controlled.
