Computer-generated block diagram

In the approach proposed here, to represent the two first-order differential equations every result of integration (state variable) is defined as a write store block in SIMULINK and every feedback signal, which must be multiplied by a gain to make up the differential equation, as a read store block. The computer-generated block diagram is shown in Fig. 11.55. 

The bond graph method defines the structure and constitutive equations of the system. Standard bond graph elements are used to build a model of the structure of the system. Suitable computer programs are available to generate the governing equations, and alternative methods have also been developed for deriving equivalent block diagrams, which can represent nonlinear systems.

For structural determination, a high resolution NMR is required and this type of instrument is discussed first. Low resolution instruments are discussed in Section 3.5.7. The most important parts of an FTNMR instmment are the magnet, the RF generator, and the sample chamber or probe, which not only houses the sample but also the RF transmission and detection coils. In addition, the instrument requires a pulse generator, an RF receiver, lots of electronics, and a computer for data processing. A block diagram of an FTNMR is shown in Fig. 3.19(a). 

A biomedical control system that utilizes a neurophysiologically-based approach has been developed for use in Functional Neuromuscular Stimulation (FNS) systems [Abbas, 1995 Abbas and Chizeck, 1995). FNS is a rehabilitation engineering technique that uses computer-controlled electrical stimuli to activate paralyzed muscle. The task of a control system is to determine appropriate stimulation levels to generate a given movement or posture. The neural network control system utilizes a block diagram structure that is based on hierarchical models of the locomotor control system. It also utilizes a heterogenous network of neurons, some of which are capable of endogenous oscillation. This network has been shown to provide rapid adaptation of the control system parameters [Abbas and Chizeck, 1995 Abbas and Triolo, 1997] and has been shown to exhibit modulation of reflex responses [Abbas, 1995]. 

Block diagram of an AC system that maintains the resultant cutting forces Fp) at a desired level F,) is shown in Fig. 1. The input to the AC system is the desired peak resultant force (F ). The AC system tries to maintain the actual peak force on the tool Fp) equal to the desired peak force (Fr). The plant consists of Computer Numerical Control (CNC) system which reshapes the command feed ifc) indicated in the NC program using acceleration and jerk-dependent trajectory generator (Altintas et al. 2011). The feed generated by the CNC is...
