A mobile control problem is studied for a class of distributed parameter systems with moving boundaries under the condition of dynamic behaviors of mobile sensors/actuators.The collocated sensor/actuator networks are considered, the measurements of the systems are obtained by sensors and are dispensed to controllers which are equipped on actuating devices.Appropriate controllers are designed according to different modes of messaging of the sensors.A corresponding mobile strategy of the sensor/actuator is presented based on the infinite dimensional abstract evolution equation theory and the Lyapunov's method.Furthermore, the relations between the proposed mobile policy and the moving boundary are proven.Simulation results show that the proposed policy is effective.
