Perform a sweep of solves varying a parameter or initial condition.

Solve a set of equations for different parameter values and/or initial conditions, and store the results in a set of runs.

Store multiple equation sets in one file (or session), providing an excellent tool for comparing results from different models.

Create user-definable functions implementing logic and looping structures to be referenced in equation sets.

Write virtually any combination Of Differential Equations (ODEs) and algebraic equations, including parameters, user-defined functions, and lookup tables.

To use this program type "DIRA" from the Nexus' Disk Operating System (DOS) prompt. Contains tools for frequency response, root locus and discrete systems. Simple transfer function based response analysis program for teaching process control. To use control station click the Control Station menu item from: "Start-Programs-Chem Eng Applications-ControlStation". Because the data can be imported from real operating processes, design tools can solve challenging real-world problems for controller design, analysis and tuning. The high order models yield transfer functions for use in custom process or for use when constructing advanced control strategies which employ a model internal to the controller architecture. Design tools will use the low order models to compute appropriate controller tuning values. You can investigate the benefits and drawbacks of different control architectures, tunings sensitivities, loop performance capabilities, and a host of other issues important to the practitioner.ĭesign tools is used to fit linear dynamic models to process data. The behavior of the process and disturbance dynamics are simulated through transfer functions you specify. Advanced strategies include cascade, feed forward, decoupling, digital and model predictive control.Ĭustom process is a block oriented environment that lets you construct a process and controller architecture to your own specifications for a wide range of custom control analyses. The basic controllers available include P-only, PI, PD and PID controllers.

The processes include level control of a tank, temperature control of a heat exchanger, concentration control of a reactor and purity control of a distillation column.

It has three major modes of operation namely case studies, custom process and design tools.Ĭase studies provides experience in hands-on plant operation and control. Control StationĪ package for teaching undergraduate process control.
