Its predictive strucutre can predict constraints violation in order to prevent them. By the expression algebraic control we imply that the conception criteria are exclusively based on the controlled variable performances. With regard to the optimal control, the conception criteria are quadratic and the performances take into account the controlled and manipulated variables. The frequency responses can be represented on Bode plots or on the Nichols chart. Setpoint change as well as various disturbances responses can be simulated.
Useful charts are available for controller tuning.
The visualisation system of the simulation results and many statisticals performance criteria allow the user to rapidly assess control performances. Data are entered in the s-domain and any types of processes can be simulated. These can be stable or instable, including delay or an integrator and can be of any order. It allows, from industrial raw data, to model any processes. The method being used is the minimisation of the square error sum of the output model.
