Energy-saving PID fuzzy controller with self-tuning parameters of hydraulic excavator

From the point of view of saving energy, a new control system, a self-tuning PID fuzzy control system has been successfully developed. According to the changing of working status, the optimal real-time PID control is accomplished by using the appropriate parameters of the fuzzy control system. According to the simulink and the experimental results, it shows that the new system is better than the common PID control method.
