This article is concerned with designing a 2-degree-of-freedom multi-input multi-output
proportional–integral–derivative controller to ensure linear quadratic regulator performance …

The integration of advanced linear parameter-varying and classical proportional–integral–
derivative control methods has attracted great attention in control of nonlinear dynamic …

It is well known that linear time-invariant controllers fail to provide desired robustness
margins (eg gain margin, phase margin) for plants with non-minimum phase zeros. Attempts …

This study considers the problem of designing a multi‐input and multi‐output (MIMO)
proportional‐integral‐derivative (PID) controller via direct optimal or suboptimal linear …

Many real world control systems usually track several control objectives, simultaneously. At
the moment, it is desirable to meet all specified goals using the controllers with simple …

This paper proposes an iterative linear matrix inequality (LMI) method for tuning the
parameters of multi-input multi-output (MIMO) proportional–integral–derivative (PID) …

The coupled tanks process is a two input-two output system. It presents a nonlinear behavior
and interactions characteristic. After the nonlinear model is obtained, it is linearized around …

This article proposes relaxed sufficient bilinear matrix inequality (BMI) conditions to design a
gain‐scheduling controller for nonlinear systems described by polytopic‐linear parameter …

The paper focuses on the problem of controlling a double-unit actuating system with a series
of actuators. Based on the conventional mid-ranging control system (MCS) with two PI …

The problem of designing insensitive H∞ output tracking controller for discrete-time systems
is studied in a unified framework by using the delta operator approach. A type of coefficient …
