Optimizing stability bounds of finite-precision PID controller structures [PDF]
, 1999 The paper investigates a recently derived lower bound stability measure for sampled-data controller structures subject to finite-word-length (FWL) constraints. The optimal realization of the digital PID controller with FWL considerations is formulated as

Optimum structures of digital controllers in sampled-data systems: a roundoff noise analysis [PDF]
, 2002 In this paper, the effect of roundoff noise in a digital controller is analyzed for a sampled-data system in which the digital controller is implemented in a state-space realization. A new measure, called averaged roundoff noise gain, is derived.

A Non-Iterative Approach to Direct Data-Driven Control Design of MIMO LTI Systems
IEEE Access, 2023 This paper proposes a non-iterative direct data-driven technique that deals with linear time-invariant (LTI) controller design by directly identifying the controller from input-output data without using plant identification.

Zero overshoot and fast transient response using a fuzzy logic controller [PDF]
, 2012 In some industrial process control systems it is desirable not to allow an overshoot beyond the setpoint or a threshold, this could be a safety constraint or the requirement of the system.
