Study on adaptive cutting control system of boom-type roadheader

in order to reduce he influence of oom-ype roadheadercuting perormance and ficiency on the sudden change of working load in difficult conditions.and based on the analysis of th effects factor of oadheader working load.the paper stated primary purpose of the cutting control s ystem was to make roadheder cutng head spedctting arm swing sped could automatically adapt the working load and also betwveen the twvo could match each other achieving eficint smooth utingConceving the dapivecortrol stategy and hariwaresystem stouctre which based on PlD neural network and a mathematical model to approximate roadheader actually working by ths me an.The sinulation analysis shoved that the adaptivecuting control method based on PlID neural network could achieve the set target value withn cutting 0.1 s which closed to zero steady-state error and met boom-type roadheader adaptive cutting needs.
