The anti-surge controller protects the compressor from surge by continuously calculating the distance between the compressors operating point and its surge limit line. of Control Systems 21 INTRODUCTION In studying control systems the reader must be able to model dynamic systems in math-ematical terms and analyze their dynamic characteristics.A mathematical model of a dy-namic system is defined as a set of equations that represents the dynamics of the system accurately, or at least fairly well. Are information system permissions reviewed and updated periodically for changes to staff, the internal control environment, or the entity? Product details, histories, and locations. In practice, there are two ways of such a transformation. But, in discrete time control systems, there exists one or more discrete time signals. These can be written as which are of the general form Here x(t) is a 21 vector (a column vector) with elements the two state variables x 1 (t) and x2 (t).It is called the state vector.The variable u(t) is the input and y(t) is the output of the system.
