In this paper an exact dynamic model of manipulator handling a flexible payload is derived by Hamiton's principle. On the basis of the distributed parameter model a position controller is designed by using Lyapunov function related to the total energy of the system. The controller can achieve the given desired link angles and suppress the vibrations of flexible payload. Using the LaSalle's invariance principle and the characteristic of the differential operator the asymptotic stability in the neighbor-hood of the desired states of the closed-loop system is proved. The effectiveness of the control strategy proposed is supported by some simulations. 2012 IEEE.

Along with the development of microelectronic process it is possible to integrate a big system in one chip. A new way to implement system on a chip is provided by the advent of FPGA. Based on Verilog HDL and the Actel Fusion AFS600 FPGA chip the speed closed-loop control system of DC motor was designed by using options of combining the top-down thinking and the bottom-up method. PID control algorithm encoder signal processing and PWM waveform generation etc were realized by the system. The results show that the system structure is simplified and the stability and reliability are improved. A solution of system on a chip is realized to some extent. It has extensive application value in engineering practice. 2011 Trans Tech Publications.

A new servo control methods for O-E theodolite is presented in this paper. The methods integrates optimally feed forward and feedback control and adopts acceleration delay compensation based on velocity delay compensation then achieves servo control of O-E theodolite effectively. Furthermore Angular acceleration sensor is applied as information resources and adaptive filter is formed to provide with feed forward control signal in the methods. For double closed loop servo control system of O-E theodolite the location correction loop and velocity correction loop are analyzed and designed. Simulation and experimental results show that comparing with traditional methods this servo control methods can improve significantly tracking precision and stability of O-E theodolite. 2010 IEEE.
