A design and implementation of a mobile robot controller on dual ARM Cortex architecture was presented. Processor S5PV210 was upper controller of ARM Cortex A8 architecture, and communicated with lower controller STM32 of ARM Cortex M3 architecture, through RS232 bus and modbus as protocol. S5PV210 processor had abundant interface with linux and QT/Embedded graphic interface, such as network, video, Wifi, 3G. STM32 could sense external environment and control the motor by interface, thus a universal mobile robot controller was designed with well-organized, good real-time, and universality.

This paper addresses the stability and stabilization problems for a class of positive linear systems in the presence of saturating actuators. The objective is to give conditions of the stability, and design state feedback control laws such that the closed-loop systems is asymptotically stable and positive at the origin with a large domain of attraction. Several sufficient conditions for stabilization and positivity are derived via the Lyapunov functions method and convex analysis in both the continuous-time and the discrete-time cases, respectively. The state feedback controller design and the estimation of domain of attraction are presented by solving a convex optimization problem with LMIs constraints. A numerical example is given to show the effectiveness of the proposed methods.
