Abstract

The invention relates to a fin stabilizer controller based on DSP. The fin stabilizer controller comprises a control circuit, a power circuit, a keyboard circuit, a display circuit, an angular velocity signal acquisition circuit, a navigation speed signal acquisition circuit and a D / A output circuit, wherein a TMS320LF2406A DSP chip is used as a core by the control circuit. According to the design of the fin stabilizer controller disclosed by the invention, the DSP is used as a digital controller, a conventional analog control system can be replaced, and the functions of acquiring angular velocity signals, performing PID operations and outputting fin angle signals can be completed.

Description

technical field [0001] The invention relates to a fin stabilizer control device, which belongs to the field of automatic control, in particular to a fin stabilizer controller based on DSP. Background technique [0002] Ships navigating in the ocean can produce swaying motions with six degrees of freedom, and rolling is particularly serious. There are many disturbance factors, such as changes in the size and direction of the sea wind, fluctuations and impacts of sea waves, the load and power of the ship itself, etc., which inevitably cause the ship to produce various swaying and course changes. The severe swaying of the ship has an adverse effect on the seaworthiness, the safe navigation of the ship, the equipment, cargo and crew on board, and poses a threat to the safety of the ship. For warships, it will also affect the hit rate of launching weapons and the take-off and landing of carrier-based aircraft. For this reason, people have developed a variety of ship roll stabil...
