A Novel Speed and Position Control Algorithm using Double Closed Loops to Stabilize Ship Platforms

Ships at sea are affected by factors such as waves which will produce a swing phenomenon. By constantly measuring the attitude of the platform and the change in position, a control system is developed to eliminate all interferences and insulate disturbances to stabilize objects on the carrier and maintain dynamic attitude reference accurately. This paper explores controllers of marine platforms to develop an attitude controller using a double closed loop speed position control system and proposes a method of variable parameter PID algorithm to deal with different tracking angles. It then builds a marine structure platform test system and debugs it using single and double closed loop systems respectively. Finally it obtains comparisons with experimental results and discusses further analysis.
