Identifiers of symbolic variables ( class sym objects) containing the f(x), g(x), h(x) functions used in the state-space description of the system. If any of the f(x), g(x), h(x) functions is not specified by a symbolic expression but by an identifier of a variable (see below), it is necessary to leave corresponding field blank. State variables have to be denoted by the x1, x2. Within them is the same as the one used by Symbolic Math Toolbox.
The convention how to write these equations and mathematical operations Symbolic expressions defining the nonlinear functions f(x), g(x), h(x) used in the state-space equations. the dimension of the system state vector x. Positive integer specifying the number of state variables of the system i.e. Block parameters System order (number of states, N) Nonlinear functions f(x), g(x), h(x) can be specified either by symbolic expressions or by identifiers of symbolic variables defined in MATLAB workspace - see detailed description of block parameters below. Where x = (x1,x2.,xN) T is the state vector, u = (u1,u2.,uM) T is the input vector and y = (y1,y2.,yP) T is the output vector of the system. The block implements a nonlinear MIMO (multiple-input multiple-output) system whose behaviour is defined by nonlinear state-space equations of the form Nonlinear MIMO system (State-Space model) Block description Nonlinear MIMO system (State-Space model) NelinSys - a program tool for analysis and synthesis of nonlinear control systems
