Proportional-integral-derivative (PID) controllers are described in most automatic control textbooks. The application of PID controllers is widely spread in automation of mechanical processes where control of motors is of concern. This paper focuses on implementation of the PID control when used for regulation of dc motors. Two basic PID structures for position regulation of armature-controlled...

this paper presents a new observer design methodology for a time varying actuator fault estimation. a new linear matrix inequality (lmi) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (fafe). the fafe is capable of estimating a wide range of time-varying actuator fault...

The problem of controlling an integral process with dead time is addressed in this paper. In particular, various practical issues concerned with the controller implementation are discussed and then verified with experiments carried out on a laboratory-scale setup where a level control problem is concerned. A comparison with a standard Proportional-Integral (PI) controller is also performed.

This article presents a comparison of controllers which have been applied to a fixed‐wing Unmanned Aerial Vehicle (UAV). The comparison is realized between classical linear controllers and nonlinear control laws. The concerned linear controllers are: Proportional‐ Derivative (PD) and Proportional‐Integral‐Derivative (PID), while the nonlinear controllers are: backstepping, ...

It is shown that proportional-integral (PI) control in the synchronously rotating (d, q)-reference frame and proportional-resonant (PR) control in the stationary (α, β)-reference frame, both with anti-windup, are equivalent if and only if their implementation is done correctly in state space and the controller parameters and the initial values are identical. It is shown that an equivalence in t...

This paper derives proportional-integral (PI) control algorithms for first-order plants with time lag. First, the effects of proportional control on overshoot and rise time are analyzed. Then these results are applied to aid in the design of PI controllers that utilize a pole-zero cancellation. New PI tuning methods are proposed for design criteria typical of those found in metal rolling mill a...

This paper presents a study of control strategies for 5-phase permanent magnet synchronous motors (PMSMs) supplied by five-leg voltage source inverter. Based on the vectorial decomposition multi-phase machine, fictitious machines, magnetically decoupled, allow more adequate control. In this paper, our focuses vector machine using linear proportional-integral-derivative (PID) current regulator i...

Closed-loop stabilization with guaranteed stability margin using Proportional+Integral+Derivative (PID) controllers is investigated for a class of linear multi-input multioutput plants. A sufficient condition for existence of such PID-controllers is derived. A systematic synthesis procedure to obtain such PID-controllers is presented with numerical examples. Keywords– Simultaneous stabilization...
