PID控制The control system, which includes structure, the composition of software and hardware, the form of PID control system and its systematic closed-loop, was used in No.4236 full-mechanized coal face of Xinlongzhuang mine.The typical fuzzy PID control system structure was investigated, and a...
To facilitate the design of the upper and lower bound functions of the system tracking performance, a typical second-order link was selected as the basic form of the system tracking performance, and the closed-loop transfer function of the second-order system is W(s)=Y(s)R(s)=ωn2s2+2...
where s and p are the feedback gains of x(t) and z(t), respectively. The output variable, y(t), is a regulated variable that is able to form a feedback loop with x(t) and z(t). The regulated variable y(t) controls the functional mass z(t) of tissue which secretes hormone ...

-order (FO) proportional–integral–derivative–FO proportional–integral (FOPID–FOPI) controller is proposed, and the integral time multiplied absolute error performance function is used. Initially, the proposed CGO-based FOPID–FOPI controller is tested with and without the nonlinearity of the ...
The transfer function is given by: ( )U z b0 + b1z−1 + b2z−2 E(z) = 1 + a1z −1 + a2z−2 (1) The recursive form of the PID controller is given by the difference equation: u(k ) =u(k −1) + b0e(k ) + b1e(k −1) + b2e(k − 2) where b0 = ...
