Design and implementation of speed control system of DC motor for electric vehicle based on PID control

In recent years, the popularity of electric vehicles has reduced dependence on oil, sparking concerns about oil supply and environmental issues. Pure electric vehicles are representative of new energy vehicles due to their low pollution, low noise, and high efficiency. Electric motors drive them and have flexibility at different speeds. PID controllers are widely used to control DC motors in electric vehicles, but there are control and circuit issues. This article proposes a DC motor PID control system based on PID control and Falstad, which reduces the number of operational amplifiers through circuit simplification while keeping the components in line with the general order of magnitude. The characteristics of operational amplifiers make them suitable for simulating known transfer functions. This article introduces the modeling and simulation methods and circuit optimization schemes of DC motors. These studies contribute to improving the performance and maintainability of DC motors in electric vehicles and promoting the development of new energy vehicle technology.
