Thruster Control System
This product is an exclusive controller to control a thruster when a ship is coming or going alongside the pier. The main function of this product is to control a blade angle of thruster to control signal which is detected control command and feedback value. And it can provide an automatic control for a thruster optimized using a follow-up control algorithm.
Detailed information
FUNCTIONS
• Auto Blade Angle Control
: Main function of this system is to control blade angle with command value. That is to say, this system controls blade angle automatically with command, when follow up control algorithm is used.
If feedback value becomes close to command value, this system doesn't transmit S/V control signal constantly but pulse signal with constant time interval and feedback value can reach the objective value quickly without overflowing command value.
Users have to set parameters with parameter setting equipment in advance and it is possible to set parameters properly in accordance with characteristics of every ship.
• Auto Load control
: This is for protecting overload in follow up operation and controlled automatically by PI control depending on set points.
If main motor actual load is more than preset load in follow up condition, the blade angle automatically changes to the angle of preset load.
• Zero Pitch System
: During voyage of the vessel, sometimes the propeller is rotated by the tide (the seawater coming into the thruster tunnel) and the pitch is moved out of the zero position. In this situation, the hydraulic pump automatically will be started and the pitch is kept in zero. When blade angle returns to zero position, hydraulic pump and solenoid valve will be stopped after preset time.
