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.

In order to reduce the size and weight of the gimbal in a traditional stable platform and correct the disadvantage in size of the payload
the paper first improves the gimbal which is an important component of a stable photoelectric platform
that also is an important factor in affecting the size and weight of a stability platform. In this paper
a closed-form solution of 3-DOF manipulator is designed according mechanical arm design principles. This manipulator is formed by a three joint axes whose extended line is intersected at one point. A standard orthogonal coordinate system is set up for each rod in the manipulator. And then
rotation transformation matrix expression is obtained. At last in this paper
the manipulator arm-shaped method for solving solutions is description
and also
each parameter of the gimbal is calculated when the photoelectric detection devices at bottom reach the expected position. Test results show that the photoelectric stability platform with gimbal we designed is smaller
lighter and simpler than that traditional. Also
the packaging and size of the photoelectric will not be affected with this open structure. 2010 IEEE.
