A total of 103 joints (46 hips, 57 knees) were replaced, including 10 four-joint replacements, 5 three-joint replacements and 24 two-joint replacements.

Control law of two-joint robot was simulated with Runge-Kuta, the result shows that control system of the robot has better ability of anti-jamming, and can stably track expected track.

So It is benefit to research the method of control problem,and it becomes one of the major topics of the field of robotics recently. In this paper, we mainly discuss the design and program driver on the two-joint underactuated manimulator and the design of PCI interface , design and program WDM driver on Windows 2000 and the total control application software of highlayer used by graph and source code .

Based on the study of CMAC net, the paper presents a online direct memory refresh learning Method for the online control of the predefined moving route two-joint plane manipulator. The computer simulation result shows that the learning method has faster convergent speed, higher control 'precision and fewer computation, and also more convinient to be realized with hardware.

We apply this scheme for trajectory tracking of a two-link two-joint planar manipulator with joint motors and distributed electro-strictive actuators.

Genetic Algorithm Tuned Fuzzy Logic Controller for a Robot Arm with Two-link Flexibility and Two-joint Elasticity

The results obtained by a rule-based proportional, integral, derivative (PID) precompensator controller applied to a two-joint manipulator are discussed.

The two-joint muscles and the superficial muscles contract more rapidly than do the other muscles in the hindlimb, thereby suggesting that both types of muscles readily adapt to quick movement.

For control engineering analyses, we utilized a mechanical two-joint link model equipped with antagonistic pairs of bi-articular and mono-articular muscles.

The distribution of fiber types of both the proximal and distal divisions of the sartoriusis is investigated. The authors attempt to compare the fiber-type composition between the two divisions and to explore the relation between the architectural features and the functions of two-joint muscle. The result shows that there is no difference in proportion of the fiber types between the divisions. The type Ⅰ fibers is about 60.7±10.1% of all the fibers counted in the proximal division, and 56.9±6.6% in the...

The type Ⅰ fibers is about 60.7±10.1% of all the fibers counted in the proximal division, and 56.9±6.6% in the distal division. There is no difference in the distribution of fiber types between the two sides of sartorius. The authors suggest that function of the proximal division is essentially similar to that of the distal one.

In this paper, plane network is described with linear equations group, and the problem for solving the capacity between two joint point is changed into concerned transforms of linear equations group. There by, the method for solving system transfer function is provided by means of matrix theory.

In this paper, simply supported reinforced concrete slabs under monotone Sransverse loads are analysed by the nonlinear finite strip method in which low order strips with two joint lines are adopted. For solving the unbalanced loads, the concept of the virtual rigidity is introduced to take account of the tension stiffening effect. Two numerical computations of the nonlinear problems are given, which reveal the initial stiffness incremental iterative method and the initial stiffness iterative method respectively....

In this paper, simply supported reinforced concrete slabs under monotone Sransverse loads are analysed by the nonlinear finite strip method in which low order strips with two joint lines are adopted. For solving the unbalanced loads, the concept of the virtual rigidity is introduced to take account of the tension stiffening effect. Two numerical computations of the nonlinear problems are given, which reveal the initial stiffness incremental iterative method and the initial stiffness iterative method respectively. In addition, measure has been taken to accelerate the convergence of the computation. The method of this paper may be applied to the extent that a small part of the reinforced steel in the slab begins to yield.
