PID (Proportional, Integral, Derivative) control is a control technique that is frequently used in closed loop control systems to regulate quantities to a setpoint of some kind. Andrew explains the math and gives an example.

In February, the Division of Biology and Biological Engineering (BBE) welcomed David Warren as its new division operations officer (DOO), charged with overseeing space planning, human resources, logistics, grants and finance, compliance, and other crucial administrative functions of the division.
Warren, who now oversees a staff of about 30 people who support 50 faculty researchers, assumed a position that was previously held by Mike Miranda, who is stepping down after 48 years of service at Caltech and 21 years as BBE’s division administrator/division operations officer. Miranda will stay on in a support role for the next several weeks to assist in the transition.

This textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering.
It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems, says a review on the Princeton University Press website.
Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling.
They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators.
