This paper presents a methodology to integrate a fuzzy coprocessor described in VHDL (VHSIC Hardware Description Language) to a soft processor embedded into an FPGA, which increases the throughput of the whole system, since the controller uses parallelism at the circuitry level for high-speed-demanding applications, the rest of the application can be written in C/C++. We used the ARM 32-bit soft processor, which allows sequential and parallel programming. The FLC coprocessor incorporates a tuning method that allows to manipulate the system response. We show experimental results using a fuzzy PD+I controller as the embedded coprocessor.

This paper presents an FPGA-based microstepping driver which drives a linear motion system with a smooth and precise way. Proposed driver built on a Spartan3 FPGA (XC3S400 core) development board from Xilinx. Implementation of driver realized by an FPGA and using Verilog hardware description language in the Xilinx ISE environment. The driver’s control behavior can be adapted just by altering Verilog scripts. In addition, a linear motion system developed (with 4 mm movement per motor revolution) and coupled it to the stepper motor. The performance of the driver is tested by measuring the distance traveled on linear motion system. The experimental results verified using hardware-in-loop Matlab and Xilinx cosimulation method. This driver accomplishes a firm and accurate control and is responsive.

Hardware Description

A high-performance vehicle multi-axis optical encoder data acquisition system based on PC104 bus is introduced. The paper puts emphases on the main function of the system module. VHDL hardware description language is used to design the modules, and ModelSim is introduced to implement logic and sequential simulation. An experiment is carried on in Altera EPF10K40 chip. Both the simulation and experimental results verify the correctness and validity of the method.

Abstract We introduce a design environment for complex multitechnology systems. The design environment supports hierarchical, multi-level and mixed-mode simulation. The design environment is based on commercially available CAE-tools including graphical interfaces for both mechanical and analog simulators. The system is built around the high-level hardware description language and interactive postprocessor tools for simulators. Linear and non-linear systems can be modelled in time and frequency domains. There is a simulation example of multitechnology system including, electronical, hydraulical and mechanical components.
