The article introduces the design scheme of a motion control card on PXI bus. A detailed description of PCI interface module, FPGA module, DSP module, serial transceiver module and analog acquisition module is also given in this paper. Tests of data transfer rate between host and motion control card are adopted, the results suggest that the PXI local bus can get a high-rate communication. The motion control card is applied to control the two-dimensional turntable of an optoelectronic imaging and tracking system. The experiments indicate that the motion control card based on PXI can meet the requirements of real-time control. The performance of control is also acceptable.

The servo system consisting of PC computer, multi-axis motion control card, servo driver, servo motor and load was constructed. The paper studied the interpolation principle and edited the procedure of linear interpolation for two axis servo motors. After the communication between PC computer and servo driver based on the motion control card, the paper edited the control interface program calling the interpolation procedure, which could realize the simulation control and real time control to servo motors. The compare results show the control accuracy of the experiment is higher.

This paper focus on a motion control card based on DSP, designed an interface communication between DSP and industrial PC. After a contrast about several methods of communication, this interface take the Dual-port RAM as the final way. This communication method regard the DRAM as the sharing storage unit, use the semaphores of the DRAM chip to prevent visiting the same address at same time on boths port and achieve the high speed communication between DSP and PC104.

Abstract A fundamental problem of mechanical motion control is that of indexing a mass reliably from one stationary position to another in a given time with as little power as possible. A quadratic time increment function is proposed and demonstrated for stepping motor control. With this function, a given motor can index a mass through a variety of index lengths. The indexing system includes a microprocessor to adjust the motor pulse timing to index the inertial load through a range of motions — each with the same maximum torque. The functions and the sizing of the motor are described. The interaction between the microprocessor calculation speed and the indexing capability is given for achievable real time control. Experimental results for a specific system are presented.

The Disabled

Autonomous wheelchairs are important tools to enhance the mobility of people with disabilities. Advances in computer and wireless communication technologies have contributed to the provision of smart wheelchairs to suit the needs of the disabled person. This research paper presents the design and implementation of a voice controlled electric wheelchair. This design is based on voice recognition algorithms to classify the required commands to drive the wheelchair. An adaptive neuro-fuzzy controller has been used to generate the required real-time control signals for actuating motors of the wheelchair. This controller depends on real data received from obstacle avoidance sensors and a voice recognition classifier. The wheelchair is considered as a node in a wireless sensor network in order to track the position of the wheelchair and for supervisory control. The simulated and running experiments demonstrate that, by combining the concepts of soft-computing and mechatronics, the implemented wheelchair has become more sophisticated and gives people more mobility.
