This paper introduces a novel bang–bang sliding control of a class of single-input bilinear systems. The sliding function is chosen via the well-known pole-assignment method for linear time-invariant systems. Importantly, the bang–bang sliding control generates a reaching-and-sliding region and a stable-sliding region, each expressed by a set of linear inequalities. Both regions comprise the eq...

–This paper deals with a small mobile device, "Seal Mechanism," with three degrees of freedom (DOFs). An L-shaped structure of Seal Mechanism is proposed. This device consists of two controlled Electromagnets FA and FB connected by two Piezoelectric actuators EA and EB with Electromagnet FC that generates a constant friction. The friction at FA and FB are alternated by an on-off control. The wh...

Large-scale binary integer programs occur frequently in many real-world applications. For some binary integer problems, finding an optimal solution or even a feasible solution is computationally expensive. In this paper, we develop a discrete meta-control procedure to approximately solve large-scale binary integer programs efficiently. The key idea is to map the vector of n binary decision vari...

This paper describes an on-off control scheme for minimum time maneuver of flexible spacecraft with vibration suppression during the slew. The method minimizes the maneuver time subject to constraints on residual vibration, sensitivity to modeling errors, rest-to-rest slew distance, and transient vibration amplitude. Furthermore, a solution is sought in the form of a plausible train of pulses, ...

Problem statement: The greenhouse has uncontrollable inputs that affect its climate, which arises the difficulty to regulate its inside temperature. The solution can be found using a multi-system approach like the Takagi-Sugeno System from which a design of a Parallel Distributed Compensation (PDC) controller is performed. However, a stability problem arises and was negotiatesd in general based...

The paper considers parametric optimal control problems with bang–bang control vector function. For this problem we give regularity and second–order optimality conditions at the nominal solution which are sufficient to: (i) existence and local uniqueness of extremals, (ii) local structure stability, (iii) strong local optimality, under parameter perturbations. Here “local” means in a L∞– neighb...

Over the last decade we have witnessed an increasing use of data processing in embedded systems. Where in the past the data processing was limited (if present at all) to the handling of a small number of “on-off control signals”, more recently much more complex sensory data is being captured, processed and used to improve system performance and dependability. The advent of systems-ofsystems agg...

In this paper the design of a controller for a relay-controlled second-order non-linear stable plant with second-order nonlinearity is considered. The task of the controller is the simultaneous reduction of plant's output and output derivative to zero with the input to the feedback system being at z;ro. It will be shown that for all initial values ot output and output derivative it would be pos...

In terms of high penetration of distributed energy resources, power systems undergo challenges on aspects of their operation, stability and control issues. Microgrids gained a lot of research interest because they have a promising future to integrate the distributed energy resources into the power systems, reduce greenhouse gas emissions and increase the reliability and security of the power sy...

In this study, a mathematical model of Anti-Lock Braking System (ABS) has been developed and simulated in MATLAB/Simulink environment using bang-bang, fuzzy logic PID controllers. The controllers were used to control the braking force be applied based on various parameters like relative slip, road condition coefficient friction between tire. result was compared analyzed. simulation showed that ...
