An electrical hydraulic control system (electro-hydraulic system) is thought to be a key component in excavator operation systems. Control methods with fixed parameters may not yield optimal performances because has various nonlinear uncertainties due the leakage and compressibility of fluid medium. Hence, novel PID controller based on improved differential evolution (IDE) introduced electro-hy...
