Abstract
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.
