According to the composition of the hydraulic system

the main components of the variable pitch system are calculated. The working principle of hydraulic pitch control system based on the physical simulation model of hydraulic pitch control system

the control process of the pitch system for the initial simulation; loading PI controller for dynamic simulation analysis on physical model building. The analysis results show that the PI control shortens the response time of the hydraulic system

and improves the control precision of the hydraulic pitch control system

and further optimizes the performance of the hydraulic system.
