ACD - Automatic controller design and automatic robus controller design   
ACD automatically calculates the parameters for well-known compensator types (P, PI, PD, PID) or alternatively for a generalized controller of user-defined order. The controller parameters are optimized with respect to a plant model and additional user options. The desired time-domain closed loop behavior is considered and may be defined graphically by a goal curve for the desired closed loop step response. Additionally, ACD provides the parameters for an ti-Reset-Windup compensator structure to avoid undesired windup effects of compensators with integral parts.

MATLAB Tutorial for Process Control   
The purpose of this tutorial is to familiarize the user to working in MATLAB. MATLAB is a high-level programming environment that processes arrays and matrices and provides a powerful graphical environment. A high-level programming environment allows the users to program without worrying about declaring variables, allocating memory, using pointers, and compiling code and other routine tasks, which are associated with languages such as FORTRAN and C. MATLAB also incorporates many built in functions that can perform a variety of complex mathematical routines, from finding eigenvalues to solving differential equations. Additional information can be found by using MATLAB�s extensive help library.

Physical Modeling   
Accelerate system-level analysis and control design with accurate and intuitive models of your physical system

The design of engineering systems requires tight integration of many engineering disciplines. To be successful, teams of engineers must collaborate using a wide array of diverse technologies. Software, in the form of control algorithms and signal processing algorithms, plays an ever increasing role in these systems. Developing software alongside the physical system results in optimized designs and the detection of errors earlier in the design process.

Nonlinear Synthesis Tools   
The Nonlinear Synthesis Tools allow the user to design nonlinear control systems using a simulation model of the dynamic system as the starting point. The simulation models can be built using MATLAB or Simulink. No symbolic manipulations are required for control system synthesis. Using a GUI, the user selects a nonlinear system design method and provides the appropriate design parameters. The software delivers nonlinear controller designs in the form of an M-file or C code. This code can be coupled to the MATLAB/Simulink simulation model to assess the closed-loop performance of the dynamic system.

Digital Pendulum Control System - Contemporary integrated system solution of classic Inverted Pendulum control problem   
The 33-005 Pendulum is a contemporary version of the classic control problem. It is large enough to be convincing, durable enough to survive the hazards of a student laboratory, and open enough for design studies. A twin-arm pendulum pivots freely on a small cart running on an elevated two-rail track. Encoders give the angular position of the pendulum and the linear position of the cart software derives velocity and acceleration for both items. A real-time kernel operating under Windows handles interprocess communication.

Educational Control Products (ECP) provides advanced laboratory equipment for the study of feedback control systems. Each apparatus may be transformed into several dynamically distinct plants so that one system does the work of many. Most systems can be easily reconfigured for simple SISO to complex MIMO operation. A high-speed I/O control board and powerful GUI-driven interface software allow you to efficiently implement virtually any controller and easily maneuver the system through trajectories to characterize performance. Experiments are provided that cover important introductory through intermediate control system principles and include complete instructor solutions. The systems are used for teaching and research in over 400 universities and industrial sites worldwide. They are used extensively in undergraduate control systems laboratories as well as graduate research and industrial motion control training.
