This control strategy is commonly found in simpler electric vehicle systems where precise torque management is not critical. Open-loop control can effectively manage torque in scenarios such as unidirectional applications or when starting and stopping motor functions, as long as the conditions remain constant.
However, the lack of feedback mechanisms in open-loop systems means they cannot correct for variances in load or environmental conditions. As a result, the torque output may not always align with real-time performance demands, which can lead to inefficiencies in electric motor operation. Overall, open-loop control offers simplicity but may limit adaptability in dynamic environments.
Closed-Loop Control Systems
