Identification and control of unstable FOPTD processes with improved transients by S. Pandey, S. Majhi

“…Thereafter, tuning rules for a feedforward and feedback combination of proportional‐integral and proportional controllers are proposed to enhance the closed loop transient performance. When the process output is distorted by measurement noise, a Fourier series based curve fitting technique is utilised for the reconstruction of true process output. …”

Syntheses of differential games and pseudo-Riccati equations by Yuncheng You

“…For differential games of fixed duration of linear dynamical systems with nonquadratic payoff functionals, it is proved that the value and the optimal strategies as saddle point exist whenever the associated pseudo-Riccati equation has a regular solution P(t,x). Then the closed-loop optimal strategies are given by u(t)=−R−1B∗P(t,x(t)), v(t)=−S−1C∗P(t,x(t)). …”

Relationship between Fujikawa’s Method and the Background Field Method for the Scale Anomaly by Chris L. Lin, Carlos R. Ordóñez

“…Fujikawa’s method leads to a sum of terms, each one superficially in one-to-one correspondence with a vacuum diagram of the 1-loop expansion. From the viewpoint of the classical action, the anomaly results in a breakdown of the Ward identities due to scale-dependence of the couplings, whereas, in terms of the effective action, the anomaly is the result of the breakdown of Noether’s theorem due to explicit symmetry breaking terms of the effective potential.…”
