[Other] distributed DL : 0: matlab 仿真程序可用于kalman滤波应用。- INTRODUCTION This example simulates distributed control of a DC-servo. The example contains four computer nodes, each represented by a TrueTime kernel block. A time-driven sensor node samples the process periodically and sends the samples over the network to the controller node. The control task in this node calculates the control signal and sends the result to the actuator node, where it is subsequently actuated. The simulation also involves an interfering node sending disturbing traffic over the network, and a disturbing high-priority task executing in the controller node
