夾持物件後的雙機械臂系統,我們可以視之為閉鍊(closed chain)的多體機械系統(multibody mechanical system)。建立此閉鍊系統的動態方程式時,應用Lagrange Multiplier定理,可以將系統的拘束方程式融入動態方程式中,然後得到拘束動態方程式;透過求解系統的拘束動態方程式,則可以求得Lagrange multipliers,我們可以透過Lagrange multipliers來控制物件的受力。由電腦模擬結果可知,透過此種理論架構,我們可以進行雙機械臂的位置及力量控制。

The objective of this thesis is to propose a new control strategy for control of position and force of dual-arm robots with parameters error.
Industrial robots often use simple PID position control. This type of controller fails when high position accuracy or contact motion is required. To cope with this problem, the concept of Sliding Mode Control and PID control are combined to control the position and force of robot manipulators simultaneously. The proposed controller is applied to dual-arm robots with parameters error.
Dual-arm robots holding with the object can be seen as a closed chain multibody mechanical system. During establishing the equation of motion of the closed chain multibody mechanical system, one can introduce the constrained equations into equations of motion, by applying Lagrange Multiplier theorem, and then obtain the constrained equations of motion. Solving the constrained equations of motion, one can get the Lagrange multipliers. We can control the internal force of the object through Lagrange multipliers. From the verification of the simulations, effects of the new strategy for dual-arm robot's position/force control had been justified.
