【正文】 he external mode SIMULINK no longer a system block diagram model simulation, but the current value of the parameter download to the target system. After the initial download is plete, SIMULINK to keep waiting for the state, only in the block diagram of the parameters change or receive parameters from the target machine began to move. When the parameters change diagram, SIMULINK calls an external interface Mfile, the new parameter values and some other signal to an external Mfile. External interface Mfile execution Inter Process Communication (IPC) channel at one end of the code, the access to SIMULINK process (Mfile execution process) and external procedures executable process together. Mfile through this channel, the new parameter to the external program. Channel the other end of the external program execution, the client writes the new value of the parameter object parameter structure. SIMULINK information by sending a message containing the initialization parameter download operation. In the C / S structure, SIMULINK as a client, serverside external procedures. Two processes can be remote, it can be local. When the client and server is remote, when, through the TCP / IP mode transmission of data, when the client and the server is local time, use shared memory, transmission of data, the system is used in the latter way. Implementation of process control algorithms, a mon simulation platform, to Jeanusers to easily add their own control algorithm or control system design, process control hybrid simulation platform provides the following three control algorithm embedded methods: 22 Applied SIMULINK controller model provides a module structure, SIMULINK provides a wide range of modules set in the SIMULINK provides a graphical user interface, as long as a simple drag and drop operation, you can use these modules to construct a plex set of controller model. In addition, SIMULINK also provides a toolbox, such as fuzzy logic and neural work toolbox of the senior class of algorithm control toolbox, use the toolbox, in bination with other modules, can build a variety of associated control algorithm model, such as fuzzy PID, PID neural work, etc., such as the fuzzy PID controller model. Use graphical user interface toolkit edit controller, intelligent controller can easily design a visual map systems. Module built using SIMULINK controller model flexibility, it looks to block diagram showing the form, and the use of hierarchical structure. Applied SIMULINK model as a visual interface controller, the controller not only allows the user to know the details of specific aspects of the dynamics, but also allows the user a clear understanding of the controller in the device, the subsystem information exchange between various parts of control interaction, for further analysis to improve the controller provides the convenience. Write C language Sfunction for control algorithm, in practice, often find that some algorithm with ordinary SIMULINK blocks is not easy to build, which you can use the SIMULINK Sfunction format support, Sfunction as an extension tool for SIMULINK has procedures format, can be used MATLAB, C / C + +, Fortran and other languages. However, in realtime simulation of the process need to SIMULINK models into C code and generates separate files, only the C / C + + language39。s Sfunction supports this feature, so the algorithm extensions must use C / C + + language, S function. Sfunction, working principle and the basic SIMULINK simulation of a similar principle, every SIMULINK blocks have input u, output y, state 23 vector x and the other corresponding to the three stages of simulation methods. SIMULINK model through the cycle of calling a particular method of each module to plete the calculation of output value, such as, update discrete state values, calculating a state of differential and other tasks. In the Sfunction with the SIMULINK simulation is provided corresponding to different stages of the callback function. phase includes Sizes, module initializes the system since they were input dimension output dimension, the number of state variables, the definition of simulation sampling time and the role of initial state variables. Output stage modular puting system output. Loop simulation phase Update modular puting system is currently updating the value of state variables. CS function not only has the C language to describe the function of the code embedded in SIMULINK blocks for the simulation in SIMULINK, and can easily be C language Sfunction module function code into pure C code.
