"本計劃發展沉浮式箱網其沉浮之自動控制，其中包含了箱網結構的動態分析，此系統由於浮體結構、漁網及纜繩所組成。首先探討浮體結構沉浮時，其浮力中心、重力中心以及纜繩張力之間的關係，如此可以瞭解浮體結構在沉浮的穩定性問題。一旦瞭解其力學特性，進一步的發展一套沉浮的控制系統，應用量測之應變及浮體上之加速度，設計一套狀態空間（state-space）線性控制系統，此控制模式可以近似此浮體、漁網及纜繩組成的非線性時變系統，這套控制的模式應用LabView 為架構，包含信號的讀入及寫出電腦以及控制方法的計算。" "The project intends to develop an automatic control of submerging and floating net cage structures. The controlled system consists of float collar, net, and anchor cable. To begin with the investigation of the floating center, gravity center and tension due to the anchor cable, the stability criterion of the net cage structure when submerges downward and floats upwards are understood. Then, a control algorithm for the submerging and floating movement is developed, based on a state-space approach. This linear time_invariant system is able to approximate the dynamic response of the float collar, net, and anchor cable nonlinear time_variant system incrementally. The control methodology is implemented on a LabView software/hardware system of which the data acquisition and software computation and control algorithm is provided."
