PID Hinf Designer

Tool for Analytical Design of a Wide Class of Industrial Controllers by H_∞ Specifications

PID H_∞ Designer is the first advanced easy-to-use web design tool for the analysis and analytical design of a wide class of controllers including PI, PD, PID, PR (proportional-resonant), RC (repetitive control), SP (Smith predictor), and many more industrial controllers based on H_∞ performance and robustness constraints. The basic supported design problem considers a simple control loop with an LTI-SISO system and searches for all controllers of a given structure with two tunable parameters guaranteeing the internal stability of the loop and satisfying one given H_∞ requirement in the form of inequality. Each compliant controller is represented by one point in the parametric plane of the controller. Points satisfying the design requirement form the so-called H_∞ region. The analytical solution to the basic design task now consists of finding the boundary of this H_∞ region. Finally, an additional integral optimization criterion (IE, IAE, ITAE, ISE) determines the optimal controller in this area. A typical design problem, unlike the basic one, contains a finite number of controlled system models (multi-model) and a finite number of H_∞ requirements (multi-objective H_∞ specification). Importantly, PID Hinf Designer can also be used even for suboptimal design of controllers with more than two tunable parameters.
