TL;DR: A method for automatic tuning of the PID process control parameters, usually called 'auto-tuning', is developed, and is implemented on a digital controller using microprocessors and applied to some real processes, yielding satisfactory results.

TL;DR: In this article, an approximation method is presented to construct an optimal state regulator for a nonlinear system with quadratic performance index, where the nonlinearity is taken to be a perturbation to the system, and a parameter @e is introduced to stand for it.

TL;DR: A new type of performance index, i.e., a weighted integral of squared error is introduced and is implemented on a small size digital controller and applied to some real processes, yielding satisfactory results.

TL;DR: In this paper, an algorithm for solving mixed-integer linear programming problems with an angular structure has been proposed, where the problem cannot be relaxed simultaneously relative to all the coupling constraints, and the decomposition procedure consists of first relaxing the problem relative to the coupling constraint for the integer variables, and then decomposing it with respect to the continuous variables.

TL;DR: In this paper, a branch-and-bound algorithm for solving mixed-integer linear programs with a staircase structure is presented, where the feasibility of the solution is always assured, but the optimality condition is checked restrictedly for the solution obtained.
