This paper describes the detailed software design of Power regulator in Fluid-power measuring experimental platform which is one kind of power control system. The function of this part mainly is adjusting heating power that based on temperature requirements, and then calculates the new power measurement. The software device mainly is composed of two parts, PWM driver and the computing element of heating power. The former control the time of heater by Variable duty cycle PWM output, while the latter calculates heating power. Through the analysis of measurement data, the results show that it’s reasonable for power measurement with this program and more accurate data can be obtained. Overall, the results fit better with the facts.

Vascular Interventional Surgery (VIS) is the common but conventional method to cure the vascular disease. Teleoperation, a promising surgery is used to protect the surgeon from X-ray radiation as well as to solve the problem of lacking experienced surgeons in remote rural areas. In this paper, a mathematical model of the damper has been built to get the relationship between the current of the coil and the damping force. According to the mathematical model, a pid control algorithm was designed to improve the accuracy of force feedback. The slave manipulator detect the force of catheter when being inserted into the blood vessels, then the master manipulator produce an equal damping force by a damper based on magnetorheological fluids. The comparison experiments between control mode with the pidalgorithm and control mode without pidalgorithm have been done to verify the performance. The result shows that the error with the pid control algorithm is small, which indicates the pidalgorithm can improve accuracy of the force feedback.
