Traditionally, control algorithms are designed without a consideration of their real-time implementation details. The performance of a digital control system, besides the sampling period, depends on many variables, such as the control loop execution time, jitter, complexity of the control algorithm etc. In this paper attention is focused on the inter-action of the parameters of the scheduled tasks...
This paper introduces a simple and efficient method and its implementation in an FPGA for reducing the odometric localization errors caused by over count readings of an optical encoder based odometric system in a mobile robot due to wheel-slippage and terrain irregularities. The detection and correction is based on redundant encoder measurements. The method suggested relies on the fact that the wheel...
This paper proposes a novel method for genetic optimi zation of triangular and trapezoidal membership functions of fuzzy systems, for hardware applications such as the FPGA (Field Programmable Gate Array). This method con sists in taking only certain points of the membership func tions, with the purpose of giving more efficiency to the algorithm. The genetic algorithm was tested in a fuzzy con troller...
In this paper we present preliminary results on systemlevel analysis of power efficiency in FPGA-based designs. Advanced FPGA devices allow implementation of sophisticated systems (e.g. embedded sensor nodes). However, designing such complex applications is prohibitively expensive at lower levels so that, moving the designing process to higher abstraction layers, i.e. system-levels of design, is a...
