A PI Controller with Dynamic Set-Point Weighting for Nonlinear Processes
The paper deals with the control of nonlinear processes with 2DOF-PI controllers. A new and practical tuning method, based on recent ideas of immersion and invariance, is proposed for the dynamic adjustment of the set-point weight. The main attractive feature of the proposal is the possibility of assigning a reduced-order linear dynamics for the tracking response beyond the nonlinear characteri...
متن کاملTime-Delayed Feedback Control Method and Unstable Controllers
Time delayed-feedback control is an efficient method for stabilizing unstable periodic orbits of chaotic systems. The method is based on applying feedback proportional to the deviation of the current state of the system from its state one period in the past so that the control signal vanishes when the stabilization of the desired orbit is attained. A brief review of experimental implementations...
متن کاملSimple Method for Calculating Backside Via Inductance
Backside via self-inductance is a critical electrical quantity needed for the design of Monolithic Millimeter-wave Integrated Circuits (MMIC). We have investigated a simple, analytical method for accurately calculating via inductance based upon physical geometry. The analytical method enables backside via process development to be tailored to meet design goals. Conversely, the sensitivity of RF...
متن کاملOptimal Tuning of Pid-deadtime Controllers for Integrating and Unstable Time-delayed Processes
A PID-deadtime controller is realized by inserting a time delay into the integral feedback circuit. Such a controller possesses a transfer function similar to a Smith predictor or an internal-model controller. Effective tuning of PID deadtime controllers remains unsolved even though they give better regulatory performance than a conventional PID control algorithm for processes with a long pure ...
متن کاملEscape Time Weighting of Unstable Stationary Solutions of Spatiotemporal Chaos
By computing 254 unstable stationary solutions of the Kuramoto-Sivashinsky equation in the extensive chaos regime (Lyapunov fractal dimension D = 8.8), we find that 30% satisfy the symmetry of the time-average pattern of the spatiotemporal chaos. Using a symmetry pruning of unstable stationary solutions, the escape-time weighting average converges to the time-average pattern of the chaotic attr...
