Simulation Analysis of Stereo Garage Control Algorithm based on ADRC

With the rapid growth of car ownership, "parking" has gradually become the hot issue of society in general. At present, people widely used stereo garage because it took small area, which had a high space utilization, and convenient operation. However, due to internal instability of three-phase asynchronous motor parameters and load disturbance factors such as fluctuations, it led to a poor robustness of the control system. Therefore, we build a system of first order mathematical model using Simulink based on Active Disturbance Rejection Control (ADRC) and made the simulation analysis by the analysis of the controller structure and algorithm. And through the comparison with the traditional PID control, we implementated the signal fast response optimization design and control overshoot.
