artificial neural networks (multilayer perceptrons or radial-basis-functions) can be expanded for nonlinear dynamic processes [47]. Real-Time Simulation Increasingly, real-time simulation is applied to the design of mechatronic systems. This is especially true if the process, the hardware, and the software are developed simultaneously in order to minimize iterative development cycles and to meet short time-to-market schedules. With regard to the required speed of computation simulation methods, it can be subdivided into

1. simulation without (hard) time limitation, 2. real-time simulation, and

3. simulation faster than real-time. Some application examples are

given in Fig. 2.8. Herewith, real-time simulation means that the simulation of a component is performed such that the input and output signals show the same time-dependent .2002 CRC Press LLC

This becomes a computational problem for processes which have fast dynamics compared to the required algorithms and calculation speed. Different kinds of real-time simulation methods are shown in Fig.

2.9. The reason for the real-time requirement is mostly that one

part of the investigated system is not simulated but real. Three cases can be distinguished:

2.9。对于实时性要求的原因主要是一个调查系统的一部分，是不是模拟，而

是真实的。三起案件可分为：

1. The real process can be operated together with the simulated

control by using hardware other than the final hardware. This is also called ―control prototyping.‖

2. The simulated process can be operated with the real control

hardware, which is called ―hardwarein-the-loop simulation.‖

3. The simulated process is run with the simulated control in real

time. This may be required if the final hardware is not available or if a design step before the hardware-in-the-loop simulation is considered. Hardware-in-the-Loop Simulation

为―控制原型。‖

2。与实际控制硬件，这就是所谓―hardwarein的半实物仿真模拟过程中可以操作。‖ 3。模拟运行过程实时模拟控制。这可能是必需的，如果最终的硬件不可用或前一个设计步骤的硬件在环仿真被认为是。硬件在环仿真

The hardware-in-the-loop simulation (HIL) is characterized by

operating real components in connection with real-time simulated components. Usually, the control system hardware and software is the real system, as used for series production. The controlled process (consisting of actuators, physical processes, and sensors) can either comprise simulated components or real components, as seen in Fig. 2.10(a). In general, mixtures of the shown cases are realized. Frequently, some actuators are real and the process .2002 CRC Press LLC
